Added Timer - great package which will make periodic tasks to work.
Timer exposes "taskDone" event, which can be triggered when
task ends it's execution.
Added first periodic task - servers information updating. By
default it will execute every 10 minutes. Configurable thru
options.
Added new options pane: Servers updating. It controls all aspects
of servers updating thing. Master server address, servers
autoupdating checkbox and autoupdate timeout values are exposed
for now.
We're now on on 0.2.0-devel :).
Fixes#29.
Now we have pooler which will pool connections (like pinging),
so there will be no timeouts due to "we have launched 100000 goroutines".
Reworked all code to use events (see Eventer). Still more work about
this to go.
Maybe more fixes I forgot.
