[SVN] r2561 (Latex)

[Charilaos Skiadas]

Updated scope for "Show labels".
Created "Enhanced Show labels", which further looks into all files \include'd into the master file pointed to by TM_LATEX_MASTER.
Will replace "Show labels" with it after more testing.

Changed:

U   trunk/Bundles/Latex.tmbundle/Commands/Insert Item Based on Current Environment.plist
U   trunk/Bundles/Latex.tmbundle/Commands/Show labels.plist
A   trunk/Bundles/Latex.tmbundle/Support/bin/labelList.rb
