Second Beta

Breaking improvements:

• major change in dependency handling -- source and package dependencies are now considered equal, so transitive source deps stop overtaking top-level package dependencies.
  May break things for users who relied on that behaviour in mixed repositories
• introduce code coverage options as cover_opts config tuple
• do not install profile-based dependencies of dependencies (stop getting your deps' meck or debug behaviour)
• lock files are sorted to minimize variations in the future and ease diffing

New:

• added proxy support to rebar3 fetches
• SSL certificate validation
• fish shell completions
• add tree command to print the origin of transitive dependencies
• aliased packages such as {uuid, {pkg, uuid_erl}} and {uuid, "1.0.0", {pkg, uuid_erl}} are now supported, where uuid_erl is the package name and uuid the library's
  actual name.
• add support for --file argument in eunit

Fixed:

• fixes to reading app.src.script (for yaws)
• minor template updates
• fixes to profiles application
• reduced memory usage (shell agent, leaks patched)
• fixes for windows (robocopy, symlinks)
• mibs fixes
• fixes to git resource handling (http, custom ssh users supported)
• hooks optimizations
• clear out all usages of 'cd'
• upgrade of dependencies has many improvements
• better error reporting and logging
• major fixes to upgrade and locking mechanisms
• fixes in recompilation of CT suites
• fixes to plugin handling
• directories looking for apps are restricted to what is documented
• escaping paths in shell commands
• edoc provider runs in a 'docs' profile
• clean provider detection of dependencies is fixed
• rebar3 pkgs output is sorted
• fix dialyzer warnings
• fixes to dependency overrides
