Adds the Rexster Console formula

This commit adds the rexster console to the list of homebrew formula. It pulls down the 2.5.0 version
from their website and copies over the lib/ and doc/ directories. Since it is a java-based
application everything within the lib/ directory doesn't need built as they are java .jar files. The
rexster script is copied over into the bin/ directory and renamed 'rexster-console' without the
version. Has a simple test to ensure the system works properly by executing the help command.
Rexster Console 2.5.0

This commit adds the rexster console to the list of homebrew formula. It pulls down the 2.5.0 version
from their website and copies over the lib/ and doc/ directories into libexec/. Since it is a
java-based application everything within the libexec/lib/ directory doesn't need built as they are
java .jar files. The rexster script is copied over into the libexec/bin/ directory and renamed
'rexster-console' without the version. That same script is then symlinked to the bin/ directory. Last
an 'inreplace' command is used to change the script to look through symlinks that Homebrew creates to
find it's /libexec/lib directory. Has a simple test to ensure the system works properly by executing
the help command.
Rexster Console 2.5.0

Updated to remove trailing whitespace from line 14 and removed version as both were brough up
through the 'brew audit'.
rexster-console: add 2.5.0 bottle.
