point compiler to the right config value for which files need to be compiled first

compiled first

Adding tests for checkouts being found & compiled

update travis s3 deploy condition

remove no longer relevant test machinery in rebar_erlc_compiler

update plugin install code

Small release fix and new plugin loading

remove script that triggered now removed retest tests

Add release-structured compiling tests

Add support for custom templates in subdirectories

- Includes tests for templates and their application

add erlydtl namespace

Provider namespaces

Now supports arbitrary commands

Using a namespace such as 'rebar3 lfe new' will look for the 'new'
command in 'lfe' namespace without the need for a 'do' provider to be
registered in that namespace.

Manually checked that 'rebar3 as <profile> <namespace> command' works,
as well with 'default' and 'do'.

Test suite still needed.

And more general namespace support

No longer needed.

Test packages

- Adding tests for package deps
- Adding conflict/override warnings for package deps
- Adding cycle detection for packages
- Adding cycle detection for mixed packages+source
- Fixing internal dependency format of package resources when converted
  to rebar_app_info
- normalizing level-order prioritization to be based on lexicographical
  sort of app names rather than traversal order (which is undefined for
  package deps)
- Fixing tests for source deps for deep cycle detection
- Fixing bugs with source deps
- Relaxed version format checks for test utils

A lot of fixes are combined in there because I didn't want to commit
non-passing code, and many bugs were found when adding the second batch
of tests as part of the original effort.

Print warning when deps are being skipped.

The case in mind here is due to conflicts, and tests have been added for
this.
