1.0.3 Added the ability to put a UTF-16 code in between $'s so that, for example $20AC$ will produce €.

1.0.2 Changed the sequence from [ck-xx to $xx$ to make the sequence less cumbersome to type, also allowing for sequences longer than two characters.

1.0.1 Fixed a regular expression to only match the last instance, this was causing the addon not to do any substitutions if an instance of [ck- already existed in the chatbox. (Example: You can use [ck-xx to make substutions, so you type na[ck-i"ve.)
