PoC of searching the Exchange Global Address List

[NeilRashbrook]

Obviously I had to make up my own API but it sort of works...

Given #906, I also looked into searching the addressbook on the server.

• ActiveSync: We can use a keyword search for autocomplete. We can't search on the server in general though for the same reasons as we can't search messages on the server.
• EWS: Most useful contact fields (address, notes etc.) can't be directly searched. There is a keyword search function, but I don't know which fields are searched (the documentation just says "commonly used properties").
• OWA: Uses a keyword search function. For some reason the FindPeople request giving me an error at the moment, which is strange because the code used to work...

I was able to write sample code for the above, if you're interested.
