Switch to Florian Shmauss maintained version of asmack. See doc/asmack-beem/README.txt for more information on how to build the asmack jar. The upstream asmack has a better implementation of XEP-0115 EntityCapabilities. So this commit remove the specific Beem implementation of this XEP and switch to the asmack one.
