Issue46 fix
Merge branch 'master' of https://github.com/corso-python-prato/share-system-team2
Modified USER_ACTIVATION_TIMEOUT to USER_ACTIVATION_TIMEOUT_SECS for issue46 fix
Merge branch 'issue46'
Fixed merge conflict with main repository
Now test_client_daemon.py can be launched like all other test modules.
test_utils.py module renamed in tstutils.py

I made this refactoring to avoid confusion with modules that test
other modules (e.g. test_client_daemon.py). since it's not a module
which test utils.py (does not even exist), it's a utility module
for tests.
Some test methods removed from TestClientDaemon to the new
'TestClientDaemonConfig' class which does not start the observer.
Speed improved of about 10-15s.
class TestClientDaemonDirState created - all tests now run in about 11 seconds
TestClientDaemon class splitted in TestClientDaemonActions and TestClientDaemonSync
removed unused imports
prints removed
style/readability: some blank lines removed
fix indentation from 8 to 4 spaces
double quotes replaced with single quotes for project consistence
some typo and english fixes
unused variable removed
comment inside docstring removed
