Fix the input file writer

This at least prevents it from crashing. Works in conjunction with https://github.com/pierrelb/RMG-Py/commit/fc4deeb082308788abe43e72e6dd0a97ee4a1eae in RMG-Py.

The original quantities were changed from getValueInGivenUnits() to just getValue(). That needed to be updated across the website input file writing scripts.

This now both writes input files and uploads them. However there are some things that need to be worked on. On the website, both the termination time AND the termination conversion need to be given or the website thinks it's an incomplete input file. Also QMTP isn't there as well.
