Create AutoItDriverServer packaged installation and update documentation

[daluu]

Based on recent issues using this server, issue #8 and #9, look into packaging the AutoItDriverServer in a simple installer (e.g Windows MSI installer file or pip install autoitdriverserver) so that it installs itself and all dependencies without user having to deal with all the prequisite install steps, and be able to run it globally any with something like autoitdriverserver [options].

Also update documentation on wiki & readme to make it easier to read & understand, particularly in terms of formatting and for novice beginner users.

Also have installer determine 32/64-bit ness of Python installation and handle registration/unregistration of AutoItX appropriately to match the bit-ness.
