Cleaned up experience profile floater

CHUI 571: Code review changes, now LLFloaterIMContainer::showStub inlines code for hiding all tab panels and then showing the stub panel. Before the function would call hideAllTabs()

CHUI-362 WIP (Torn off conversation name is highlighted when selected in conversation list with different conversation showing in message panel): implemented method for a switch off tabs (switching to an invisible state)

EXP-1504 : Move the tab opening stuff to lltabcontainer and out of llbutton. Added an xui param to allow drill through tabs. Set that param for build panel only.

Added new attribute image_flash to button.xml which sets an image used for button icon when button is flashing.
Pointer to this image is stored in member mImageFlash from LLButton and is used in LLButton::draw(). There are two
ways an image can flash now - by making changes in color according to flash_color attribute or by changing icon from
current to the one specified in image_flash. Second way is used only if the name of flash icon is different from
"FlashIconAbsent" which is there by default. First way is used otherwise. Used new selfmade orange icons for
flashing tabs.

add floater flashing, fix group icon sizes, fix click,some code cleanup, ect.
also I remove mIconCtrlWidth/Height since its kinda useless - mIconCtrlPad do the same thing...
IconSize will be btn_height-2*mIconCtrlPad - simple and good enough.
