Do not compile nodetool escript

This removes the dependency on lib/compiler in an OTP release.

More error logging

rebar throws away some error messages, e.g. the ones generated if the yecc compiler is broken.

simplenode.reltool.config: use default sys-level mod_cond setting

Makefile: call Dialyzer with -nn flag

As discussed here
http://erlang.org/pipermail/erlang-questions/2012-December/071135.html
change the reltool spec to use the default sys-level mod_cond setting.

This speeds up 'make dialyzer' for the common case of Erlang/OTP built
without --enable-native-libs.

Fix unicode

rebar_core: fix sub dir association

Update rebar repo urls

Change simplenode template files to work on more platforms

Support reading mustache 'lists' from files

Implement 'rebar help CMD1 CMD2' and extend common 'rebar help' msg

This commit add support for reading mustache 'lists' from files, so you
can use the list section functionality when templating things.

An example of the list syntax is as follows:

{package_commands, {list, [[{name, "riak"}], [{name, "riak-admin"}], [{name, "search-cmd"}]]}}.

Then you can, for each of the list elements, render some text:

{{#package_commands}}
chmod +x bin/{{name}}
{{/package_commands}}

When developing Riak, we have found bugs and other issues due
to the number of platforms we support.

Here is an overview of the changes:
  -  Fix command-line syntax for commands to work on *BSD / Sun
  -  Add chkconfig and getpid to nodetool
  -  Replace platform specific 'kill' commands with a nodetool
	getpid method
  -  Fix RUNNER_USER settings to work on *BSD

* allow plugins to print help message for implemented commands
* append core rebar.config options to common 'rebar help' message

Fix basho/rebar/issues/286

Support environment vars with unicode characters

Add missing variables

- add overlay_vars=, target_dir=, and tests= with short description

bash-completion: add missing options and variables

- add missing short and long options

rebar.config.sample: fix escript_emu_args sample

Makefile: fix 'clean' and add 'distclean'

Change zsh completion script

bash-completion: add generate-appups
