[lazarus] CVS Changes

[Marc Weustink]

Hi,
some minor updates:

+ Added invalidBreakpoint image
    Also invalid breakpoints are shown different in the editor.

* Reorganized uniteditor so that breakpoints can be added or
   changed external
    This is needed to show invalid or disabled breakpoints and
    for breakpoints created through the breakpoints dialog.
    One won'tsee changes yet, since it also requires some changes
    to main.pp, which is reorganized at the moment.

* moved breakpoints events to notification object
    More than one object requered the TBreakPoints.OnAdd event
    so the events are now handled by a separate object.
