Support within() block

[moose-byte]

It would be awesome to use the current working directory set in within() blocks. Right now it only uses the absolute path.

This is the syntax I am thinking of

within host.properties.tomcat[:home] do
  template 'setenv.sh', './bin/setenv.sh', 0755
end

Currently that would put my file in ~/bin/setenv.sh

I did at support for within block to the master branch. Please reopen this issue when anything goes wrong.
