templater: return error, don't throw, if git or hg fail

symlink extra test dirs and compile from there instead of from root project

root project

compile source from the symlinked directories under `_build`

get correct compile paths included in module info

update sample config to remove unsupported rebar2 options

don't traverse into subdirectories looking for beams

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makes some cases clearer (`rebar3 as as as as` is no longer valid).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`
