Various fixes
    
    - Fix dependencies for devel subpackage.
    - Explicitly declare dependency also on libs-sql subpackage where required, so we can save one extra cpu cycle during the upgrade (...).
    - Bat subpackage used to rely on files in %%_docdir for operation, move them elsewhere. Fixes also Fedora 20 unversioned %%_docdir feature.
    - Make sure any package combination results in installed license files.
