- Automation: Added xor(a,b) boolean logical function to utils.lua (jfs)
- Automation: Various changes to karaskel.lua and karaskel-adv.lua: (jfs)
o Added some debug-calls (which are disable by default; aegisub.output_debug is replaced with a do-nothing function (you can change this in karaskel.lua)
o The regular aegisub.output_debug is aliased to aegisub.output_warning, in order to always be able to show real warnings, in case something goes wrong
o Fixed bug, triggered when a line had a style not defined in the subs. A warning is now shown instead.
Originally committed to SVN as r4.
