Added Linux Version - UI/Window, and Crash FIxes

Just a quick update:

Main fixes go to the fixing of rare crashes under export, since application was not running in background and when exporting you select from a window dialog, while application remained  frozen on background,  ended up crashing in rare instances when export was triggered,

• App is still completely Portable
• Resizable windows added
• UI fixes for resizable window:
• Window can be maximized now
• Added Linux version and  Windows version naming
