[Pafgbt] paf wiki page write permission

[Rick Fisher]

Karl,

Were you able to resolve the issue of wiki page write permission from 
outside of NRAO?  To continue to build on Roger's original wiki page, 
let's limit the theme of the new page to planning for GBT tests.  I've 
added links between the two pages.
