Add 'ability_id_active' attribute to filter
Until now, only the type of ability could be filtered with activity, and id only for unit who have ability, same if she's inactive.
This adds running the WML schema validation in travis. It also updates the schema itself and fixes a few WML errors so that core and all campaigns under all difficulties pass the schema validation.
- Allow for variable substitution in filter tags (mostly)
- Fix real not matching numbers like .5
- Support x,y=recall,recall
After this commit, there are no schema errors in the tutorial.
Currently this is disabled by default
Use --validate command-line argument to enable
The following new features were added in the schema format:
* Union, intersection, and list types
* Keys can specify a union of known types on-the-fly
* Key and tag names can include wildcards (* and ?, glob-style)
* Tags support any_key=yes, which means unrecognized subtags will be ignored
* Tags and keys support deprecated=yes (unimplemented)
* Specify max=infinite instead of max=-1
