ver1.01a Backend rewritten

Compared to the old version, this release introduces a new output comparison engine that compares respective lexemes, instead of raw text. This way the comparison becomes insensitive to the white-spaces and tolerates minor differences. Next, cptest now is able to behave correctly with floating point numbers by correctly ignoring too precise digits. Finally, with the new engine a support for mismatch highlighting was implemented.

• Lexeme-based comparison
• Floating-point number support
• Mismatch highlighting
• Excessive line feeds don't screw up the rest of the output comparison anymore.
