[Issue 662] Translations retouch

Fixes overlaps and text running out of boundaries.
Fix a ton of run-time warnings about UI.

Cleans up some related code, probably looks nicer with space changes off.. though this is a pretty straightforward change.
Comments out code that still exists in xmls or might likely be added in future.
Each piece tested quite a bit.
Finish up last commit

Fixes the segfault that was accidentally overlooked because voice decided to not return after the first run as I worked on all the other warnings
Thanks to Latif Khalifa for the VoiceMultiInstance debug setting which enabled me to use voice again.
Byebye run-time warnings from llgivemoney.cpp
Fix logic in toggle_active_speakers.
Restore DEV-12255 patch

Refresh the snapshot when calling show after instance exists (IE: Via Keyboard shortcut)
Should never have been removed in the first place, the purpose of 7faa19b29792b558a50b1da2bdfc483f6cc839dd was to have an explicit click to refresh, this patch requires an explicit click.
This does NOT break keeping the same snapshot while switching settings
Snapshot floater aesthetics

Restores the cancel button with new functionality! In Freeze mode, it will exit freeze! Otherwise it will just close the floater as it used to do.
Lines up everything nicely, and removes overly complex tool tips.
Does not change or remove any existing functionality.
Fix Issue 689: ATTACH_NECK and ATTACH_AVATAR_CENTER are missing strings
More UI warnings fixup stuffs
Merge branch 'Cupcake' of https://github.com/LightDrake/SingularityViewer into Frosting
Add Pathfinding UI from v3

Added libpathing to LLPHYSICSEXTENSIONS_INCLUDE_DIRS
llviewermenu updated a bit to be closer to v-d/rlva. Best viewed without space changes.
Updated llresmgr.cpp from v-d to "handle special case of input value being zero"
pipeline update: hideObject, restoreHiddenObject, hideDrawable, and unhideDrawable added.

Thanks to Henri Beauchamp for some UI code touchups, thanks to Zi Ree for Rebake notification.
Thanks to Mobius Ryba and Ansariel Hiller for the V1-style pathfinding icons.

Note: When opening from pie menu object selection is lost, unless the floater is already open..
This provides a more reliable reproduction of the bug we've been having with inspect.
Warning fixfix~
