[Gpsbabel-code] cotoGPS is back

[Olaf K. <O.B...@t-...>]

Dear all,

i've made the necessary changes on cotoGPS to get this format working. The 
main reason for problems with testo were the structure definitions. In coto 
some field has been defined using types from coldsync/palm.h. There we can 
find some definitions with the "long" datatype. In the 64-bit world long, 
unsigned long... has a quantity of 64-bit. 

Some remarks:

* option "trackname" removed because this can be done with track filter
* reference data (gpx) changed

O.K.
