Quick input definition by string

[connorcoley]

Fixes #444 and fixes #372

This adds a very simple parsing tool to "quick add" an input. Only two patterns are supported and they are quite rigid:

(1) [AMOUNT] of [NAME] (2) [AMOUNT] of [CONCENTRATION] [SOLUTE] in [SOLVENT]

Any thoughts on making it more flexible? I'll leave it to Steve if he wants to get fancy with regex. This is at least functional and does seem to add a bit of convenience.
