#544 Add systray integration for Linux

[dg1727]

Please consider adding a systray icon and menu on Linux, per the freedesktop.org specification.
If user privileges are a problem, then maybe:
1) a configfile option could be added to specify which users get a Privoxy icon in their systray, and
2) the menu could start out read-only, but operations that require superuser privilege would prompt for a password the first time (in each X login session) they are used.

For troubleshooting the actionsfiles, the systray approach would be a big improvement over requiring a user to keep the enable/disable bookmarklet open and to manipulate the logfile manually (keeping a terminal window open to clear the logfile when desired, etc.).

Thanks for your time.

Thanks for the suggestion.

I thought the following was already on the TODO list, but apparently I forgot to add it:

100) Create a cross-platform Privoxy control program and retire
the win32 GUI. Integrate support for Privoxy-Regression-Test,
Privoxy-Log-Parser, Privoxy-Filter-Test, uagen and similar tools.

It's now on the list.

Note that there's no need for a password prompt as the user running
the control program can be put into privoxy's group, or the permissions
of Privoxy's files can be modified so the user has access.
