Add 404 logging + Regexp matching for redirection rules possibility.

[eprochasson]

Hello,

I added a few feature I was looking for.

• All 404 that can not be matched with a redirect rules are logged and presented to the user. That's highly valuable when revamping a website, to make sure no URLs are lost in the process (and easily track the missing one and take action).
• 404 logged can easily be transformed to a Rewrite rule
• Added Regexp matching and replacing. It uses basic php function, seems to work quite well.
• Added caching of previously encountered rewrite rules (to avoid hitting the database to often when a rewrite is common)

Since it adds a few new columns to the modRedirect table, so it might not works perfectly as an update to previous versions. I'm sure there is a way to handle that properly though. I was also unable to update the Schema for sqlsrv. Finally, as I don't speak so many languages, I only updated the English and French lexicons.

I took the liberty to add my name to the list of contributors :) and pop the version number since I believe this is quite a major change.
I also understand that, as it's quite a major change, it might not really respect the original idea behind Redirector. If it's uncool, I'll just fork it but I'd be much happier to integrate that directly in Redirector.

Ha, I just commited a small security fix, to strip [ and ] from the URL (to avoid MODx code injection, since the replacement URL is parsed).
