[c.nicos]

hi, guys!
Awesome editor!

please add NSIS(Nullsoft Scriptable Install System) script syntax support, thanks!

Have you looked at https://github.com/SublimeText/NSIS? I've noticed that a lot of syntax highlighting packages are out there, just not included as part of the default sublime.

Thanks man!
I'll give it a try. Although I trust the official packages more...
