Colecovision: Improved Keypad Mapping and Fast BIOS Patch

[jfroco]

• Allow mapping of the 9 and 0 keys, as well as buttons 3 and 4 of the Super Action Controller, to the RetroArch gamepad.
• Add a configuration option to use the keyboard for 0-9, *, and # (for players 1 and 2).
• Add a configuration option to patch the BIOS for faster booting (3.3 seconds).
• Fix small typos ("coleco" and "contend").

Notes:

• This PR affects only Colecovision emulation
• This PR adds the 0 and 9 keys, as well as Super Action Controller buttons 3 and 4 to the right analog stick:
  • Ref: Impossible to press 0 or 9 on ColecoVision number pad #49
• The Super Action Controller adds button 3 (equivalent to the 0+1 keys) and button 4 (equivalent to the 1+2 keys):

  • Ref: Colecovision super action controller buttons #160
• For those using a keyboard, there is now an option to use 0-9, *, and # directly:
  • Player 1: 0 to 9, - and =
  • Player 2: numeric pad 0 to 9, / and *
• This PR adds a configuration option to patch the NTSC BIOS directly in the code for Fast Boot (3.3 seconds).
