Tidy up options documentation
deleting .gitmodules old leftover
fixes empty variables used in output messages

there where variable names left over after the code refactoring
they have now correct names or are filled, messages stay the same
fixes #138
correct tomb_key variable usage in logs
make sure the old manual is not confused with the actual 'man tomb' #150
avoid using Tomb's PID in temp files and double the random #150
Remove fatally broken failure :)
runtests now returns 1 if at least one error has occurred, fix #153
use swish-e and not the debian-specific wrapper, fix #136
added documentation about pinentry to manual, fix #115
