Blur effect adds correctly, textField "pops" and displays in its current position, keyboard displays correctly
TODO: move textField to editing position (i.e. above keyboard); Return key on keyboard acts as expected (on keyboards with a Return key)
Crash trying to move textField after editing
Added "pop" animation to Input vc for hashtag input
Editing textField still doesn't show in correct place, but other than that, everything works
Finally(!) got textField editing animation working as desired (by faking it!)
Removed extraneous NSLogs used for debugging
