Here is a zip file with the addon. There are really only 3 files other than the libs: "Config.lua", "Squire2.lua" and "Localization.lua".
I have also included text files with the output of findglobals: Config_Globals.txt, Squire2_Globals.txt, and Localization_Globals.txt.
Please note that I didn't write this addon
All I did was update it for 5.0.0.4. It's frustrating because everything seems updated and ready to go except for this one stupid error.
Also, I did at one point go through and rename all of the local variables that were "_" to something else; however, that did not seem to change anything, so I reverted back.
