tag: further improvements

[siddharthvp]

• simplified Twinkle.tag.callback.evaluate, reducing the lines of code as well as making to easier to maintain. Now if you add subgroups to some tags, you no longer have to update anything in this function.
• file tags: convert tag-specific prompt dialogs to subgroups for better user experience

@siddharthvp This looks mostly fine from reading through the code, although I'll hold off on testing and doing a thorough review until the merge conflicts are dealt with. I'll probably be squashing them given things like the leftover console.log and the includes/indexOf.

until the merge conflicts are dealt with.

Done.

Needs some changes to get working

[Amorymeltzer]

@siddharthvp In addition to the fixed required fixes in the above review, the changes to file tagging simply don't work. I didn't look into why, but they all end up as undefined and a number of the parameters are repeated. Compare the changes made with the current tag module to those made with this version

It's certainly different, but I really like the changes here! Smart and nifty, cleans things up real well, and should make it much easier to maintain 🏆
