OOP-izing gSourceEdit

This week I've been away from home without a web development setup. So I decided that I'd work on gSE for a little bit. It's been needing a coding overhaul which included implementing it in full OOP (Object Oriented Programming, for those who don't know) as the current code base was becoming a tad bit difficult to manage. As a result, the fully OOP'd version should be in the repositories soon (which can be found on the gSE project page). I'm hoping this will help me iron out some more of the many bugs that it has at the moment and of course, make the code much easier to manage and more readable than it is currently.
