Added ption to start basho bench as part of a node by calling basho_bench:main/1 not just as a standalone node from command line, the default option is the original standalone
FAIL_MSG behaviour to depend on included/standalone mode

If basho_bench is running standalone, call halt(1) on fatal errors
like before.  When included in another node, kill supervisor for a
more graceful exit.
Don't crash if basho_bench is already loaded

Add ability to put files and verify numFound for search

Specifying `{file_dir, Dir}` will create a list of all files in `Dir`
(non-recursive) and PUT them using the basename of the file as the
key.

Specifying the operation `{search, {Query, NumExpected}, P}` will run
a search with the specified `Query` and verify that the returned
`numFound` matches `NumExpected`.
