Pin requirements to specific versions

[deadbits]

Right now none of the libraries in requirements.txt are pinned to versions. If any library gets updated, this could break the entire application.

The usual suspect I've had trouble with is the pycrypto library, which if it varies between versions, can cause a ton of problems in all sorts of low-end dependencies

Thanks, @deadbits

I will take a look at the requirements version to specify a version or to set an interval of working version.
