correct typo in README link to non-root usage doc
[doc] (GH-103) Document user accounts for `r10k deploy`
Merge branch 'issue/master/gh-103-document-deploy-user-accounts'
[cli/puppetfile] Only pass :trace to TaskRunner

Previously, passing `-v` or other commands when running `r10k puppetfile *`
could result in this error:

    r10k puppetfile install --help --trace
    Error while running: #<RuntimeError: Unrecognized options: help>

This was due to overly greedy code passing too many options. This commit
restricts the options being passed to the TaskRunner.
[cli] (GH-164) Make `--help` globally respected
Merge branch 'bug/1.2.x/gh-164-global-help-flag' into 1.2.x
Merge branch 'bug/1.2.x/gh-165-puppetfile-verbose-option' into 1.2.x
Merge branch '1.2.x' into 1.3.x
Merge branch '1.3.x'
[cli] (GH-158) Document loglevels in --help output
Merge branch 'feature/1.2.x/gh-158-document-loglevels' into 1.2.x
[cli/deploy] Remove duplicate --help options

In commit ca35e33 a global --help flag was added so individual commands
don't need to implement a --help flag in every location. This commit
removes the redundant help code in deploy/environment.
Merge branch 'maint/1.2.x/remote-duplicate-help-flags' into 1.2.x
Merge branch '1.2.x' into 1.3.x

Conflicts:

This closes GH-154 and GH-68.
