More server fixes

[njbooher]

Fixes:

• Only imports the GUI module if GUI mode was requested.
• Removes the build directory. Currently build/lib/packman/bin/PACKMAN.py is out of sync with packman/bin/PACKMAN.py and setup.py is preferring the stale copy of it from the build directory over the up to date one
• Add GitHub's recommended .gitignore for python projects
• Remove the dist and egg directories since the .gitignore ignores them

Can you please brief me about the deleted files?

Also, Sorry for not adding import inside the if condition.

The deleted files are the contents of the build, dist, and py_packman.egg-info directories. These directories are automatically generated by setuptools when you run python setup.py install or similar. They don't need to be stored in the repository.

The build directory being in the repository is causing an issue when the server installs the package in a virtual environment. python setup.py install sees that there's already a build directory and installs the files from it rather than from the packman directory. This is a problem because the build directory in the directory is currently out of date.

The easiest way to resolve this is to not store the build directory in the repository at all.

Thank you. Will this affect the twine upload? Because every time I upload a new version on PyPI, it requires me to match all the previous versions with the existing ones on the PyPI.

If this will not create any problems with PyPI (pip), I will go ahead with the merge.

I don't think it will affect it. Make a new release after merging to test.
