Preparing alpha state

#4 feature branch.

**Changeset**:
- [x] phpcs2 (dev; current alpha tag broken for composer)
- [x] dropped namespaces (compat issues)
- [x] dropped abstract sniff (autoloading issues)
- [x] fixed testsuite (reporting issues)

**TODOs**:
- [x] fix issues reported by test suite (#9: out of 11 tests 7 fail)
- [x] look at self-test (reports itself incompatible)
- [x] look at symfony and zend framework test (they should be reasonably compatible)
- [x] test non-git install
- [x] prepare feature review (assumed incomplete)
