Init script doesn't check if globaleaks is effectively started

[fpietrosanti]

The init script, implemented at #66, does not check properly if globaleaks is started or not, by reporting the error.

For example during a debugging session globaleaks was not starting due to this error:
Traceback (most recent call last):
File "bin/startglobaleaks", line 144, in
GLSetting.parser.add_option("-s", "--storm", type="int",
NameError: name 'GLSetting' is not defined

but the init script was reporting started:
www-data@vz203:~$ /etc/init.d/globaleaks_dev start
Starting Globaleaks...
started.

Evilaliv3 reported that this should be related to the way we startup globaleaks under "nohup"

fixed with commit eb27dee and some other commits on GLBackend
