Bash completion file.

Hello Aaron,

here is a bash completion file for poretools.

By the way, I have a draft Debian package on <https://github.com/charles-plessy/poretools/tree/debian/master>.  If poretools is to evolve quickly in the short term, maybe it is a bit early to make an official Debian package.  But I hope that this draft package may be useful to others.

Cheers,
