Second beta release of Vacation 1.2.7.1

Vacation 1.2.7.1 beta2 is the second beta for the first bug fix only release in the 1.2.7 branch.

This release just fixes up some issues that Coverity revealed, none of which appeared to be harmful.

NB: If you compile with GCC 4.6 and see a complaint about orighdr being set but never used in rfc822.c don’t worry, its already fixed in git and will be in the first RC (assuming nothing bad is found in this version).

Please grab this beta release and test it and report any problems!
