Default client alarm management improvement

[shubla]

Default client allows you to set custom alarms.
However it doesn't memorize the path that you selected the alarm from last time.
So for example if I choose custom alarm for a moose from folder hnh/alarms/moose, and then one for a boar, it sends me into folder documents instead of hnh/alarms!
Easy fix, memorize the path and attempt to open that folder if it exists.
