(issue54) Merge branch runafterinstall
There is now an NSIS Plugin that executes the Software after
installation using COM in the shell of the current user.
With the way over the shell there is no inheritance /
token management required. As it is impossible to
drop all privileges of a token granted by UAC and
still be able to reelevate the Token again with another
RunAs call later this round trip over the Shell was
necessary.
