Allow user information for importing database to be filled in manually.

Remove unix-only os module related commands (os.getlogin, etc. are unix-only and
fail on windows user machines.)  Raise an error if the username and email cannot
be found from git alone.  The user is then asked to fill in that information
manually within the importOldDatabase.py script.
Script for creating RMG-Py thermo and kinetic libraries from a valid chemkin file.
Change exception handling for finding username/email from git in importOldDatabase.py
Remove typo. (Connie must have had hats on the mind!)
Change-detection in importOldDatabase script.

It attempts to detect changes since the last import, and set the history items
accordingly. Not really working yet, but I think a good start..
Some work on the importOldDatabase script
Some debugging change-detection in importOldDatabase script..
Change detection working! (I think)

Database needs a lot of tidying up though, and the default units etc.
and pretty printing should probably be changed.
Changing ä to a in Aäron Vandeputte's name due to encoding problems.
Extended Database for Nitrogen and Tri-Radicals
Merge remote-tracking branch 'bbuesser/master'
Removing duplicates from Dean and Bozelli library
Updated output folder to RMG-Java at commit bb21002
Updated kinetic libraries with adjlists containing paired electrons (new Py format).
Updating thermo libraries with new adjlists.

GRI-Mech3.0 and primaryThermoLibrary retained as originals due to nitrogen changes.
Fixes to adjlists in DFT_QCI_Thermo.  Commented out cis-butene.

RMG cannot differentiate between trans and cis-2-butene.  Remove cis-2-butene.
Commented out GRI-Mech3.0 version of OH in primaryThermoLibrary. Use AcTc instead.
