CHUI-896 FIXED Line flashing and FUI button flashing not working correctly for CHUI notifications: added flashing of the line item after conv. floater opens

CHUI-905 (Viewer crashes while using Insert keyboard key in chat): Problem was because when insert was used at the end of a string of text, this would attempt to delete something past the bounds of the string...as a side effect the size of the segment was increasing even though the string length never changed. The segment size would be greater than the string size and would eventually cause an invalid read outside the bounds of the string.

1) when preference is "Pop up" - added toast according to Kurt's comment from 22/Dec/12;
2) fixed line item flashing and "Chat" button flashing in other cases according to original matrix.

CHUI-875 (Viewer experiences a 10s delay on dnd (do not disturb) notification loading): For now adding logging when reading from persistent notifications and from dnd notifications.

CHUI-851 ([CHUIBUG]Focussing issue and unresponsive tabs when focus is brought back to the HUB): Now when pressing enter a docked nearby chat floater will be focused and the conversation line item will be selected. When the nearby chat is not docked then only the floater will be focused.

CHUI-895 FIXED Show toasts for messages if conversation is collapsed to Input bar(regardless of other prefs).

CHUI-846 ([crashhunters] crash in LLFontGL::maxDrawableChars): Added logging for bug to further track down problem when it occurs. Need to debug further based off information.

CHUI-885 (View Profile,Send IM and Add friend are not functional in context menu for allowed or banned users of the parcel.)

CHUI-888 : Fixed! Overload setVisibleAndFrontmost() so that we set the focus if requested (was dropped in the shuffle before).

CHUI-877 : Fixed! Ignore the Vivox buffy names right now and avoid invalidation avatar name cache when seeing a difference with vivox

CHUI-871, CHUI-738 : Fixed! Name tags existence was using a bogus test. Using a boolean for existence and straight logic, no intermediate string

CHUI-881 ([CHUIBUG]Viewer crashes when user drag and drop the participant from the people floater to the one of the tool bars): Problem was that the item dragged from the people list was not of type inventoryitem. Instead of casting to an inventoryitem and checking if the item being dragged is a widgit, instead look at the cargo type (which also specifies that the dragged item is a widgit but doesn't need to typecast).

CHUI-878 FIXED Torn off conversation window width can be reduced and lose vertical scroll bar: manually setting of the floater's minimal size

CHUI-880 FIXED Show Button panel if floater is torned off. Don't show Conversation floater in Mouselook, if Nearby chat is torned off.

CHUI-873 FIXED [CHUIBUG]Torn off nearby chat with message panel hidden has huge bottom padding when opening in mouselook mode

CHUI-857 Nearby chat opens as torn off on first login: changed initial setting for nearby chat docked state

CHUI-843 ([CHUIBUG]Suggested alteration to toolbar_panel in floater_im_container in CHUI): Adjusted button layout in conversation floater.

CHUI 796 (User doesn't get all messages in 'do not disturb' mode): Now IM DND notifications will be stored as p2p, ad-hoc or group. When loading these notifications upon app start ad-hoc/group notifications will launch the conversation log and play a sound.

CHUI-864 ([crashhunters] crash in LLConversationLog): Found a probable cause. It is likely that the user was missing the user settings variable called 'KeepConversationLogTranscripts.' If this variable doesn't exist or is deleted then the CHUI viewer would try to extract data from this non-existent variable. Resolution, now perform a check to make sure the 'KeepConversationLogTranscripts' settings variable exists before extracting data.

Added check in LLVOAvatar::idleUpdateNameTagText() to account for case where mNameString is literally "" (two quotes)

CHUI-620 FIXED Clear the highlight when auto-selecting new conversation or when text is entered into the message panel.
