Release 1.0 (No longer beta maybe)

Prima has come a long way since the last release, and a lot of changes have been made to all areas of the program. As a result I might miss some stuff in this changelog, but i'll do my best.

+Added CSS and a new stylesheet
+Added better support for image importing and manipulation
+More stable
+Better rendering code (The interface no longer hangs when rendering previews in the editor (It still hangs when exporting for now, fix coming soon 😛 ))
+New Nodes

~Reworked the node layout in the code, relying more on bindings. This result has made the interface much more consistent and less prone to bugginess.
~Reworked a lot of the backend code for better efficiency and to add more features

-Removed some irrelevant nodes and classes

Bug reports, issues and suggestions are greatly appreciated, Thanks 😄
