check lang inconsistences, especially cor, aze, khm, lao

[alanfgh]

The strings for cor (Cornish), aze (Azerbaijani), khm (Khmer), and lao (Lao) were missing altogether from docs/generate_sphinx_conf.php on the server. Also, the last 13 items in that file were lacking English names for the languages.

I fixed these problems in the versions that I checked into the repository, but in our current workflow, those changes won't make it to the server. Someone with write access to the server would need to copy the fixed array from a dev repository (or GitHub) to the server copy.

It seems like it would be a good idea to alphabetize the arrays in the files touched by docs/add_lang.sh to make it easier to check for consistency across the different files. We also should make sure they all have icon (flag) files.

There is one misspelling in app/models/sentence.php: the code for Malagasy is given as "mgl" instead of "mlg". Otherwise, the lists of languages match up.
