update erlydtl compiler to output to _build, add simple test

Bump to alpha

Fix namespace regressions

This adds some more convolution to command parsing, unfortunately, but
makes some cases clearer (`rebar3 as as as as` is no longer valid). It
unfortunately disallows using $REBAR_PROFILE along with `as` in a rebar
command.

update all examples in providers to use rebar3

parse `rebar3 as foo, bar task` correctly

fixes #238

fix code path update for deps

escript provider

apply profiles and overrides for an app's opts to the base opts

profiles are failing to be applied

relevant to #224 and #233

makefile tabs replace spaces and force clean

Fix handling of ct results

* Return error on failed and/or auto skipped tests
* Print all results for quiet repeated tests
* Sum results of repeated tests

Change PLT name and directory

switch from loading modules to read compile info to using `beam_lib`

Add debug statements to dialyzer provider

New template defaults

Previously dialyzer stored the project PLT in ./build/, which meant the
same PLT was used for all profiles. This could mean partial rebuilding
of a PLT when switching between profiles.

fixes #216 and #220

fix for profiles_remain_applied_with_config_present fixes #212

Don't include directories when testing subset of ct suites

preserve state when compiling directories with a `rebar.config`

ct fixes

rebar state from propogating appropriately

shorter build dirs

move `_logs` and `_cover` to `_build` dir

to `as` used to generate them
