source: configure @ 4a0614e

Cleaned up Makefiles + configure: Cleaning up bitlbee.pc, removed the second
piece of libevent probing code that mysteriously appeared (?), better handling
of storage backends, an SSL module is now always included (so BitlBee can be
compiled again when building without MSN- and Jabber-support (http_client also
depends on SSL libs and can't be disabled)), oh, and fixed a compiler warning.
