new behavior:
- depreaction comment (/** @deprecated */) is added always
- @Deprecated annotation is added only when presented in .class file
rationale:
- both deprecation comment and @Deprecated anno produce "Deprecated" attribute
- adding annotation to members deprecated by comment (old behavior) is actually incorrect
- adding comment to members deprecated by annotation may be incorrect but is acceptable (there is no way to tell if a member was deprecated by sole annotation or both by annotation and comment)
- additional configuration option is therefore no longer needed
- test classes (src/test/*) moved to separate root
- stray .class files dropped
- binary files (bin/, dist/full/, dist/obfuscated/) excluded from the repo
- .classpath and .gitignore updated accordingly
- invalid import statements removed
