- new property: affinity (might/magic) since in mods it is impossible to
rely on odd/even numeric indexes
- property commander is now part of hero class
- fixed starting armies of some heroes, including Bron #1602
- (debian) added vcmi-dbg package with debug information
- proper randomization of hero secondary skills, fixes#1603
- second capitol will show up as disabled immediately #1604
- proper deserialization of boost::variant
- empty file will no longer crash JsonNode parser

compiled first.
- changed format of modSettings.json, VCMI should properly update file
on the first run.
- implemented property "defaultTavern" that acts as default value for
"tavern" entry in hero class and town formats.
- loading of all objects (including H3 objects) will be directed by mod handlers
- common base for all handlers accessible from mod system (IHanderBase)
- json format changes: use struct with string ID's instead of vector
- fixed some gcc/clang errors and warnings
- fixed several cases of memory leaks and invalid memory access (mostly related to usage of bonus system and/or identifiers resolution)
Note that right now loading is much slower than before due to excessive json validation (or not fast enough validator)
- removed duplicated json loading code in handlers
- simpler and mod-friendly handling of combined artifacts
- reorganized CCreature to avoid huge number of fields in one structure
- artifact iconIndex should work
- new file with hardcoded string constants: lib/StringConstants.h

- - hero army and creature upgrade names are resolved using new system
- - faction names and creatures in towns are resolved using new system
- (linux) replaced build_data.sh with hopefully better vcmibuilder script
