Split the stop duration field into two inputs

[lgouzin]

The stop duration item could be split into two fields, one for values, and one for time units. The current way is a bit confusing, does it take an 's', does it defaults to seconds, etc..

Is this request for the Trajectools QGIS plugin?

[lgouzin]

Yes that's correct. Did I enter them at the wrong place?

[anitagraser]

Yes but don't worry, I moved them to the plugin issue tracker now
