Added framerate limit and menu options.otherfixes

- Fixed sprite being displayed in upper left corner on some roms (all
else working, but sprites are not fully working)
- Added framerate limit with just a few lines in TinerasNES
- Added some menu options/text (File->nestes, File->Close) etc.
- 'Close' properly closes roms and waits for a new one to be loaded
- Added color tv static back in when rom is not open...pretty cool!
- Changed criteria for (is the sprite on the scanline).  Excluded
sprites on line 0 (memory.memSPRRAM[i] > 0) instead of including them
with '>= 0'
