bltins refactoring: replaced LOGGER_NAME to __name__
Temporary removed tests, because their code no longer corresponds to the reality, and incorrect code obstructs with reading a pylint log. Later I will write new tests.
pylint: some mute for C0103
Fixed quotes: ' -> "
Updated README
README.md: fixed link syntax
splitter: fixed task_id logging after the split
gns.service: removed validators copypaste
gns.service: addad validation for core.import-alias and core.fetcher
Merge pull request #37 from mdevaev/master
