*Implemented .mif support.**

Detailed change list:

• Command line switch '--mif' enables the generation of .mif files instead of .mem files.
  Because '-m' is already in use for '--mem-size', so there is no short switch.
• Divided function write_hex_file into 3 variants: mem, hex, mif.
• The generation of the mem-file header does not depend on the output file extension.
• Incremented version number.

Questions:

• Maybe it's nicer - in the view of coding style - to use a big multi-line string for the MIF header instead of multiple calls of print(..). Should I change it?

Further optimizations:

MIF files support compression. It's possible to store recurring data words in one line. This could be used to store consecutive DEFAULT_JUMP instructions in one output line.

Oh, here is a open PR. Is this PR ok or should I improve anything?

Sorry, I forgot about this PR and haven't been monitoring the GH site. I've merged it in with a change to print 8 words per line. I haven't verified that this works in Quartus but it follows the docs on MIF.
