Build database from intercept pointers declaration

[kymckay]

Reads the intercept pointers declaration file to generate the database.py file.

Closes #25

Just noticed a slight issue in that operators aren't included (==, !, etc.)

[kymckay]

Fixed that, the issue now is that the unit tests are case sensitive against the error message which contains the operator names. Unfortunately the operators in the parsed file are all lowercase.

One solution would be to edit the unit tests to ignore case (or I suppose it would be better to convert the operator names to lowercase in the assertEqual calls). It would be less pretty, but not the end of the world.

Couldn't you just hard-code those in the generation script?

[kymckay]

The symbols? Yeah not a bad idea

Merged in 3820b60.

I did some minor changes to clean PEP8 and make it a single commit, and merged it to master.

Thanks a lot @SilentSpike for this commit, much better than manually doing the work from intercept side.
