[BREAKING] Code improvements

[RigglePrime]

See the updated readme for more details.

In short:

• Removed the need for parentheses
• All country codes have been converted to ISO 3166-1 alpha-2 (two letter codes, such as SI, US)
• Refactored a bunch of code
• Added writefile (does what it says)
• Added writeln (write and add a newline)
• You can now do write hello\n and it will write a newline. It's just a replace so it ignores \\n (will write a backslash and a newline)
• The fact that press releases all buttons is now documented
• You can change layouts on the fly
• You can now loop for a set amount of times (loop 10)
