Adds install target which does not need make_bundle.

Hi,

as already discussed I changed the makefile to allow installation without make_bundle.

As make_bundle is picky and does not work everywhere I made the 'non bundled' install target the default and moved the bundled version to a target called installbundle. I hope this is ok for you? My idea was that that "make && make install" should now work on most installations without problems.

Greetings,
