Multiple minor fixes:

- 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
- fixed some compiler warnings
