Added the possibility to specifiy which data size you reference in T.MEM trees,
by adding an argument to T.MEM that specifies its size. BYTE, WORD og DWORD.

Added a char type, which is a 2 byte value (although intentionally treated as 4 bytes sometimes).
Characters are represented by a 2 byte codepoint, and strings as an array of characters (with no size at position -1).
