[Repairs] Repair centers directory

[Mel Chua]

I took a stab at cleaning up wiki pages, and was partially successful - 
it needs plenty of help.

http://wiki.laptop.org/go/Repair_center_locations - a lot of this 
information is really out-of-date, so please help correct it! I am 
trying to keep the entry for each center to 1-2 links max, so that 
people can just go directly to that link for more information about an 
individual center once they find the location they are looking for.

http://wiki.laptop.org/go/Repair_centers - it is cleaned-up all the way 
down to the http://wiki.laptop.org/go/Repair_centers#Meetings section. 
Can someone take/clean/migrate the content below that to some other, 
better section?

Also, something we should start...
http://wiki.laptop.org/index.php?title=How_to_start_a_repair_center&action=edit

Just a few strawman stabs at trying to make the vast amounts of 
information we have here coherent to outside viewers.
