.. added to the splitter handle context menu
.. also took IntervalItem.h and IntervalTreeView.h from MainWindow.h
coz I was getting pissed with recompiling everything when changing it.
Thats why so many other files have been changed in this commit.
Fixes#338.
All are harmless but for the sake of clarity have
fixed them all bar a couple;
- Lucene grumbles about signed/unsigned conversion which
is/isn't valid depending upon the version of CLucene you
compile with. Either way it is harmless.
- QxtScheduleView has a bunch of issues, but since it is a
third party widget its better to leave it unchanged.
Find interval dialog will now allow you to add
intervals by time or distance (e.g. add interval for
every 10 minutes or every kilometer).
Since there were three menu options all doing similar
things, they have now been consolidated into a single
dialog.
