Fixed normal bug EXT-5885 ([HARD CODED] - The busy response should be localized. hard coded in llviewermessage.cpp).

- It wasn't hardcoded in llviewermessage.cpp, but xml which contains it is not localizable. Added string with default busy message to strings.xml
and used it in LLFloaterPreference::cleanupBadSetting().

Review #114
This (mostly XUI) change moves the prefs checkboxes out of the nearby media panel and into the prefs floater. The "Sound" tab is now the "Sound & Media" tab, and its layout has been modified drastically to match https://docs.google.com:443/a/lindenlab.​com/Doc?id=ddznhrqn_34kcxdz8f3#​Preferences

'General' pane

Remove code for aspect ratio controls from LLFloaterPreference.  (The XUI had already been removed.)

- changed "control_name" for view with log path to the "InstantMessageLogPath"
- also changed a line editor state from "disabled" to "readonly" to have a chance to scroll text to see full path in this field.

Review #89

This implements the changes Sam wanted in order to reduce the confusion over media enabled-ness, in particular:
- "Media Enabled" pref now only controls "AudioStreamingMedia"
- No more "tentative" state
- New "Music Enabled" pref
- First run dialog controls Media and Music (Sam, this is a change from your request...I think it works better)
- Put a reflection of the "Media Enabled" checkbox in the Nearby Media Floater
- Get rid of the "AudioStreamingVideo" setting altogether (whatever used it, it should now obey "AudioStreamingMedia").

The prefs floater was unilaterally reverting any changes
made by other UI.  This fixes that by making squirreling
away the current settings an explicit operation, and
cancel now happens explicitly on close(), but only if
a flag is not set (as is what happens when you hit OK).

Reviewed by James.

Reduces chance of future UI bugs related to UI size.
Discussed with Richard.

code. All help should now go through the new help server, via the Help
Browser floater. There should no longer be any custom "?" buttons in
the UI - all <button> and <notification> XUI references relating to
custom help buttons have been expunged.

(I previously extracted all of the help strings from notifications.xml
and passed these to the doc team to include in the help server pages.)

I have checked that none of the XUI elements that are removed here are
still referenced by any C++ code. I've also confirmed that there are
no new notifications removed that I have not already passed on to the
doc team. And I've also done a pass through the UI to make sure that
all of the floaters still look as they should. Finally, I've confirmed
that the new help system for floaters and side panels still works.
