Swear Words filter seems to be overmatching

[Sitzilla]

There seems to be an issue with the swear words filter overmatching. Words that I have found that are counted as swear words include: ("me", "and", "an")

Example:
ExudeData.getInstance().getSwearWords("crap this is me and my friend");

Discovered this is because the isValidWord method checks if the String of swear words contains the word passed in. So for example "as" will return as a swear word because it is contained in "asshole".

It seems to me the solution is to tokenize the string of bad words (ex. "...,asholes,ass,ass monkey,..." becomes [..., "asshole", "ass", "ass monkey", ...]), iterate over each one and check for equality.

@uttesh I'll make a fork, make this change, and open a pull request on it
