Maps should handle garrisoned units (for example for sea nomad map)
Now that #2877 is done, we can have nomad maps and it would be nice to be able to have garrisoned units in maps. This can be done quite easily via scripts (thanks to discussions with leper). The attached garrison.diff patch interprets such scripts and initializes the garrisoning.
An example of such a script is given in the attached skirmish map Sicilia_Nomad.xml which is just a slightly modified version of the Sicilia_(2) map. To test it, copy the Sicilia_(2).pmp file to Sicilia_Nomad.pmp and you are ready to play the first ever 0ad sea nomad map :-)
