Moved time select box to own widget
use timehelper instead of time
use a single line per import
move the time regexp to the timehelper
Parse the time regexp in the timehelper

This removes all other places of the regexp
Call it timeRegexpString to make clear its not a real regexp
wrap the anonymous function in parentheses
Rename timehelper.parseWithTimeRegexp to parseTime

It's not important that it uses the time regexp internally
Merge pull request #350 from voidus/timeBoxWidget
