Port search terms to exile tools

[thirdy]

I've started porting the search terms to use exile tools. A working demo can be seen here:

http://thirdy.github.io/search/index.html

where the search term it uses is the ff:

https://github.com/thirdy/thirdy.github.io/blob/master/search/terms/itemtypes.txt

The exile tools documentation would help in understanding how to do this.

Not sure yet where I'd create a new repo or just use this one, note that we can rename this repo.
