Summary: Redundant filelist creation on multiple invitations

Initial Comment:
If i invite 2 or more buddies to a session, Saros actually expensively 
calculates an identical filelist for each invited buddy and this in parallel, 
so the performance is seriously impacted on non SSD-harddrives because of the 
parallel filesystem access of multiple OutgoingInvitationProcesses.

There is no caching mechanism for the creation of the 
projectExchangeInformation Objects (expensive!). 

I will take care of that and introduce an optimization just for this case, when 
a user invites multiple buddies at once (by using a wizard) > in this case it's 
acceptable to create the ProjectExchangeInfo (or at least the filelist XML) 
just once. This will increase the speed of inviting multiple buddies at least 
by 10 seconds which should be notable.

Even on a very fast network, local hash calculations take considerable time.
