Changes affecting backwards compatibility

Breaking changes in the standard library

• base64.encode no longer supports lineLen and newLine use base64.encodeMIME instead.

Breaking changes in the compiler

• Implicit conversions for const behave correctly now, meaning that code like const SOMECONST = 0.int; procThatTakesInt32(SOMECONST) will be illegal now. Simply write const SOMECONST = 0 instead.

Library additions

• macros.newLit now works for ref object types.
• system.writeFile has been overloaded to also support openarray[byte].

Library changes

• base64.encode and base64.decode was made faster by about 50%.
• htmlgen adds MathML support (ISO 40314).
