Removed code duplication between testsuite and commandline tools. Also restructured source code of the tools.

Merged mail-raw implementations of sieve commandline tools and the testsuite, thus removing duplicate code.

Significantly improved handling of old/corrupt binaries and revised matching implementation in the process.

Properly implemented the code dumper. Dumps are now printed in a stream. The individual opcode and operand implementations no longer use printf()s.

Almost finished implementing the store action. But, I still get strange errors when the mail transaction commits. Mail is stored though.
