Search Enhancement

[kato13]

I added AND and OR support for all registered users. meaning you can now search:
Methanol AND still
And get results of threads which contain both of those words.

Although when attempting this I discovered something I did not know about the forum search.

When I searched for "still" and it returned nothing, I thought the search was broken. It turns out that is how the search is designed. Common words, called "stop words" are excluded. "Still" was in that list (due to it's more often used meaning) so I removed it.

The following words are still restricted. Please let me know if you feel any others should be removed.
