Undescriptive error message when user isn't part of LP team.

[Ryan Kavanagh]

Bazaar should provide a more descriptive error message when the user is trying to upload to a launchpad team, yet isn't part of the team.

In this case, I tried to upload to the bazaar.launchpad.net/~5-a-day/5-a-day-data/main branch, but got an error message:

% add-5-a-day 199441

bzr failed with error code 768

To fix this, I needed to join the 5-a-day launchpad team. In a case like this, I think a more descriptive error message would be:
bzr: ERROR: Cannot lock LockDir(lp--1217704244:///~5-a-day/5-a-day-data/main/.bzr/branchlock): Transport operation not possible: You are not a member of the 5-a-day team.

This is primarily a bug in Launchpad's bzr server, not Bazaar itself.

This somehow got fixed.
