  <issue>
  Change setup.py to list the version as 1.x-dev for versions installed from github
  As suggested by @themperek, it would be neat if cocotb behaved like this:
  ```
  > pip install git+https://github.com/cocotb/cocotb
  > python -c "import cocotb; print(cocotb.__version__)"
  1.4.0-dev
  ```
  
  </issue>
  <code>
  [start of cocotb/_version.py]
  1 # Package versioning solution originally found here:
  2 # http://stackoverflow.com/q/458550
  3 
  4 # Store the version here so:
  5 # 1) we don't load dependencies by storing it in __init__.py
  6 # 2) we can import it in setup.py for the same reason
  7 # 3) we can import it into your module
  8 __version__ = '1.3.0'
