This commit reverts namespace for the plugins and uses a module prefix
"deluge_" in it's place. The distribution package name remains the same
for now but will also be considered to use a prefix to help find the
third-party plugins e.g. Deluge-{Plugin} and the pluginmanager will
strip the prefix for displaying.
The change is a result of problems trying to package Deluge with
pyinstaller and the pkg_resources namespaces is not compatible.
Testing alternatives to using the pkgutil or PEP420 (native) namespaces
did not yield any joy either as importing eggs with namespaces does not
work. [1]
At this point importable eggs are considered deprecated but there is no
viable alternative yet. [2]
