Add a Select2 drop-down to `add-shows` and `edit-show`. The Select2 enables displaying inline language flag images, this feature deprecated by the native `select` drop-down element on some browsers. Change run existing TVInfo source language lists through validation (removes ~4 bad items), de-dupe list, get the native names, English names, and three letter abbr. Change remove marisa-trie requirement from language_data/names.py because nothing in SG calls a function that requires it. Change update some flags.
