wordmatching algorithm

Adds a word matching algorithm (Aho–Corasick for those who want to know) that searches through all .tw and .js files in src/. The speed difference between running the sanityCheck with or without this algorithm is negligible. I didn't notice any difference.

The only limitation is that I can't output the line where the phrase is found, only the file. But since modern text editors have a search function that shouldn't be a problem.

To add new phrases add them as new line to devTools/spellCheckDictionary.txt.

The only thing left is to convert the content of devTools/spellCheck.txt to my format and add it to devTools/spellCheckDictionary.txt. Or maybe have two files, one for the big base dictionary and one for manually added phrases? If someone knows how to convert that automatically I would really appreciate it.
