Loaders: make short_name and description attributes.
Fix a couple of docstrings.
Fix another bug in YamlLoader.

Now the conversion in load() gets applied also if None was to be
returned in the case of a non existing key.
Fix docstring.
Modified Reimporter to only import changed tasks.
Extend a docstring.
Use a somewhat nicer touch.

It doesn't wipe the content of .itime and .import_error files
in the (admittedly strange) case there is something interesting
inside.
YamlLoader: add gen/GEN among the files to be checked for changes.

It is inspected to build subtasks.
Typos.
Removed length and binary response in the fake remote service.

The real remote service in async library changed (binary response was
unused, thus also the message length became unnecessary). The fake
remote service (implemented in cmstestsuite) needs to account for
those changes. For the tests to continue working.
Added some files to the installation to fix cmstestsuite.
Mark TODO as such.
SS: missing import of Task.

I don't know how things managed to work, but definitely we want
to import Task if we use it (kind suggestion by pyflakes).
Add TODO.
Optimize dropping the whole database.
Sample config: use "python2" instead of "python" as process_cmdline.

"python2" is expected to be more common, since it is used in all
shebangs.
Unit tests for logservice.
Renamed RunTests to RunFunctionalTests.
Partial pep8 on cmstestsuite.
Running unit tests automatically.
