Update git submodules

* Update dictionaries from branch 'master'
  - Remove abbreviations from Thai hunspell dictionary.
    
    Reasons:
    1. They are not present in other spellcheck dictionaries (such as en).
    2. To add all abreviations would not be much different from adding all
    possible combinations of 2-3 Thai consonants. This would make misspelled
    abbreviations come as correct to the spellcheck anyway.
    3. Adding only the most common ones can cause confusion to those using
    less common ones, as the spellchecker will suggest the more common
    abbreviation. It is also nearly impossible to determine if an abbreviation
    is common that it should be added or not.
