Some improvements to new project creation.
1) Default settings for a new project are now loaded from a file
instead of being hard-coded in fstimer.timer.
2) If you make edits to one page of project settings, press back
and then press forward, the edits now persist after the window
is reloaded.
3) A new window for specifying project type and number of laps.
4) Number of laps is now an attribute of the PyTimer class.
5) projecttype and numlaps are saved in the .reg file
Note that numlaps has not yet been removed from the pre-timing
window, so specifying it in project creation currently will
have no effect.
