Atari FontMaker Code

Added a view export function
- You can export as binary, or in various text formats
- Select the export region of the current ViewEditor_AddPage_Click
Fixed a bug when mega copying text from font 3 and 4

Fixed right-click selection in the view editor, the correct font bank is now selected.
Double right-click now cancels the paste operation (in both the font selector and the view editor)
Switching between graphics modes does not redraw the fonts but only copies the new font bank

Reorganised the code into sections.
All event handlers are located in FontMakerForm.cs
AtariFont.cs contains the font data.
AtariFontRenderer.cs renders the fonts in mono and color.
All fonts are cached in a bitmap in mono and color, so when switching between there is no need to re-render the fonts.

changed the way how resource files are handled - no more unnecessary saving to disk
+right click to font index in view window decreases font index number
