Source Editor and Character Editor Complete

Time for a quick update on the development environment.

The Main code editor is almost complete (I think). I have written it from scratch, using a canvas, to allow me total control over it.
It has full syntax highlighting that is changeable, dependent on the assembler being used and code folding. I still have to implement the source navigation and search facilities.
The project manager is also in place and 80% functional. As I work on other parts of the project that impact on it, I will make the changes then.

The basic character set editor is now finished. At present, it only saves to binary format, so the character set can be directly included in the source, but I may also add an export facility to create source code.

The preferences window is being created as I do each area of the main program, therefore, I have done the Code Editor and Character Editor sections only, so far.
