moved the CipherSuite enum to the correct package. it was forgotten in org.inchat.common.
completed the tests.
implemented the rsa key generators.

typo
added javadoc.
finished the rsa cipher and the tests.
remove the bouncy castle provider if it's already in the system. this allows to test if the provider is added in any case correctly.
