r25510: {website} Dropping the remaining orbot projects Nathan hasn't responde (website/trunk/getinvolved/en)

Author: atagar Date: 2012-03-07 15:32:27 +0000 (Wed, 07 Mar 2012) New Revision: 25510 Modified: website/trunk/getinvolved/en/volunteer.wml Log: Dropping the remaining orbot projects Nathan hasn't responded about GSoC mentorship, and his last email indicated that it was unlikely. Jake gave a blanket 'yea, I can mentor any of those projects' which is nice, but doens't fill me with much confidence that we have a primary mentor for anything Orbot related. I'm on the fence about if we should remove them or flag as simply not being eligible for GSoC and mostly decided to go this way due to lack of communication. If Nathan replies later then great.
