i) fixed a bug in anrem-local that made the local calls not working inside the rules of a target
updated TODO
i) implemented issue #1 solution as anrem-target-group* set of functions
ii) added sample demo to show how to use anrem-target-group functions
i) added possibility to get a list of modules that have content subscribed to a group, this can be useful for building the -I switch of a rule that uses the group as dependency
i) modified automatic dependencies algorithm now avoids the creation of the useless .mkdep placeholders
i) tidy up code and add some comment into hooks.mk
ii) removed test code from sample and left a working sample
Merge branch 'anrem-autodeps' into devel
i) added improved auto-deps algorithm that does not use any placeholder files, nor touches the dependency output provided by the mkdep-hook
