Better Project Manager

[voylin]

The default project manager which we have now works, but needs more improvements to actually be useful to use. Features like the sorting have to be improved a little so it can go both ways.

Things to note:

• Don't over complicate it (Keep visuals minimalistic and clean/simple);
• Must use the default theme (Default theme at this point is still a work in progress).

I have already created a base version, it has some bugs, especially when importing new projects, sometimes importing certain projects twice for some reason. As of now it works and this is good enough to be in the first milestone release.

Edit: This is added to the Version 0.0.1 milestone as it is bugy and needs fixing/re-work anyway before we can release the first version of GoZen

Made a very simplified version of the project manager. It still needs some extra features, but it's probably good enough for now.
