Added warning for modules/ dir

@mikkergimenez Has added functionality which means for users that already have a modules/ directory they now get a nice error and onceover doesn't blat it silently (nice)

Fixed function mocking for rich data

This fixes #159 and means that functions that are mocked now reliably return the data type that they were passed in the YAML. Also gets around some big errors that you can get by passing strange strings

Allow custom templates and forcing

New features:

• #157 Added the ability to use custom templates
• #158 Added the ability to tell r10k to force override locally modified modules

Added :before section

This option allows for more thorough mocking of functions that need to behave differently based on certain fact conditions.

Props to @LMacchi for this feature

Fix Caching regression

#154 Was introduced with the last release, this remediates that issue and also finally fixes the way onceover does caching of deleted files. Thanks to @philomory for finding the bug

Fixed caching of dotfiles

This release fixes #115 and adds a large amount of automated acceptance testing which should make things a fair bit more robust.

Issue #113 may be fixed by this but it has yet to be reliably replicated so I doubt it.

Fixed modulepath delimiter on Windows

Fixes #143

Add support for :control_branch

Onceover now supports the :control_branch feature, it just does a simple find and replace based on the branch that you currently have checked out.

Thanks to @Nekototori for this feature

Fixed #140

This release fixes a regression as described in #140

Thanks @GeoffWilliams

Fixed #131
