Boilerplate cleanup

[Micalobia]

The code has a lot of boilerplate, and I'd like to reduce it some by making helper functions and such

For example:

• Every list generation from multiple fields is pretty much the exact same code
• All the version checks could be a function call to something like minimum_accepted_version and maximum_accepted_version
• A lot of request.args.get calls could be simplified (example below)

if request.args.get('excludedetails') and request.args.get('excludedetails') == 'true'

# 'false' could be replaces with just '', or not be there at all, but this is clearer to what's happening
if request.args.get('excludedetails', 'false') == 'true'

I'd be willing to do any or all of these changes, just not sure which ones are wanted, so any feedback would be nice.

I have an example branch in my fork here, where it's branched from master.

Edit: Link change, branch update
