EXT-6840 : Miscellaneous Avatar Debug Textures Floater improvements

Changed "Debug" into "Debug Textures" on right-click menu.
Added "Debug Textures" to right-click menu for self (so you don't need to CTRL+SHIFT+ALT+A).
Prettied up the dump textures console output.
Fixed a bug where component textures for yourself were showing up when viewing others (you shouldn't see any component textures when viewing others).
Enlarged debug textures floater a bit.
