Improve SDL IDE experience

[Fusioon]

• Print IDE build time & version on non windows platforms (time is determined during compilation & version is from cVersion constant)
• Linux: add implementation for BF_DEBUG_BREAK & IsDebuggerPresent() so Runtime.FatalError now won't just close the debugged application
• Fix importing of folders in IDE when path ends with /
• Implement clipboard with mime types (working/tested on arch & ubuntu) without 'bf_text' mime type the line duplication feature does not work
• Make autocomplete window clickable
• Fix recent file selector (have to pass modifier keys to newly focused window)
• Set SDL property to allow system screensaver to work
• Reduce radius in which clicks are considered double click (sdl default is 32, changed to 5)
