GeoLocationDialog bug; JCalendar; SSR started

I've found a bug in GeoLocationDialog, coordinates are not displayed correctly (probably, due to rounding, users cannot enter certain values, for example 1 deg 2 mins 0 secs renders into 1 deg 1 min 59.9999 secs). This needs to be fixed!

After looking for nice widget for calendars that will come handy with SALT and SSR plugins, I've found JCalendar that is not too big and looks quite nice.

I've also started working on SSR (Sensor Service Request) plugin. I hope with lessons learned from SALT, I'll go more swiftly.
