Move __version__ into setup.py

[znatty22]

Issue

Right now version is set in the wstler package init and then imported in the setup.py file. Because of this, when someone tries to install the package via pip install ., a bunch of module not found errors result. This is happening because Python is trying to import wstler and all of its dependencies before any of the requirements are installed.

Solution

Move __version__=foo into the setup.py file
