syncing categories and other issues

Hello there,

I have now worked through the libmimedir and found the bug that was
preventing me from importing mutliple categories. I have already sent
Sebastian Rittau a patch for it. It just one line so I hope it will be
checked in soon.

It basically works, but gpesyncd is having problems with the new
database layout for the calendar.

However there are some questions that I would like to have confirmed
befor I check them in.

- I need to add a function to libgpepimc which gives out the name of a
category to a given id. I hope that's all right.

- Could it be that in libgpepimc in file db.c at line 48 it should be

 struct gpe_pim_category *c = g_malloc0 (sizeof (struct gpe_pim_category));

instead of

 struct gpe_pim_category *c = g_malloc0 (sizeof (c));

 or does it make no sense (there is another line like that at around line 217)?

- Is the use of libeventdb from now on the standard? If yes, then the
gpesyncd will be dependent on the most recent version of it and
therefore on the new database layout.

- Why is the weather on the world summary the coldest in New Zealand?

Happy coding!
Martin
