AoS/OpenSpades compatibility

[bztsrc]

Hi,

Here's a little patch that adds vxl (AoS, OpenSpades) to the export menu. The only difference is, libvxl allows saving arbitrary sized maps, but the original AoS needs a fixed sized map. This option configures libvxl in a way that the saved map will be 100% guaranteed to be compatible with the original vxl spec.

The current code allows for import/export of arbitrary sizes, since AoS 1.0 Battle Builder uses non-standard maps. Maybe a checkbox or input fields to specify size would be better.

I don't know about that, all I know that others had issues so I was kind to add this little patch for them. I don't play AoS myself, and I have no reason to question my friends complaining about the map loading. It could be that AoS was fixed in the meantime.

Maybe a checkbox or input fields to specify size would be better.

Yeah, and would also require a significant redesign of the UI (currently there's no form at all when exporting). This patch aims to be as minimal as possible, that's why it just adds a new "format" to the menu, nothing else.

But do as you please, it is your project. If you can use this, that's fine, if you can't no hard feelings :-)
