Affected files:
* Configuration.py
* Database.py
* HandHistoryConverter.py
* fpdb_import.py
and setup.py to a lesser extent.
Logging requires a configuration file when initialising the class. If we
are executing from outside the source tree, this file is not present.
Catch config parser's error and try to provide the logging config file
from debian package path.
Update symlink target to match python-support from latest Debian and the
oncoming Ubuntu versions.
* It seems that fpdb gets installed into /usr/share/python-support/
while many other packages end up in .../pyshared; fixed the symlink
target
* Fixed mail address in changelog, which now is the correct one
* Added postinst script to make fpdb.py executable again. This hack
is needed because dh_fixperms didn't allow to ignore the script's
permissions and the file is located in .../fpdb/ along with all the
other fpdb modules
* Told package manager to create /usr/bin/fpdb symlink pointing to
fpdb.py so we now have an application named "fpdb" in the system
