Fix the docs for glance_image.endpoint_type

The endpoint_type option was added in version 1.7,
so the docs need to state this.  Also the the description
is too brief.
Always return a list even if its empty.
portage: Add support for --changed-use

The `--changed-use` flag is an improvement over `--newuse` because it
does not trigger rebuilds for USE flag changes that would not affect the
installed package. Its use is generally recommended over `--newuse`.

Signed-off-by: Dustin C. Hatch <dustin@hatch.name>
service: use self.changed in service_enable_rcconf().

This sets the "changed" result of the module when a rc file is modified.
Previously only --check mode would show that it was going to change.
Can override each role's install path

Defaults to the system wide `roles-path` when `path` is not specified in the
provided `role-file`.  An example installing nginx to a relative path specified
by the `role-file`.

Formation, Format, and Constiency

There should be a period after "Various release-X.Y branches exist for previous releases". It should read "Various release-X.Y branches exist for previous releases." This should keep the Branch Info listings consistent.

This changes the get-attr function slightly, and lets the module specify whether a param is needed and auto-fails if it is not present. A module can now verify params like so::
 $params = Parse-Args $args;
 $result = New-Object psobject;
 Set-Attr $result "changed" $false;
 $path = Get-Attr -obj $params -name path -failifempty $true -resultobj $result

or

$params = Parse-Args $args;
 $result = New-Object psobject;
 Set-Attr $result "changed" $false;
 $path = Get-Attr -obj $params -name path -failifempty $true -emptyattributefailmessage "Oh man. You forgot the main part!" -resultobj $result

slight tweak in how the powershell module converts to json in order to support nested objects (allows for more complex facts, among others)

This script gathers some extended facts on windows hosts in a json array attribute called "ansible_interfaces". This info is needed for some network-related modules I'm working on. Required the update to powershell.ps1 to return deeply nested json objects.
