Closes #4822
docs(guide/migration): fix internal link
docs($sce): ng-bind-html takes an expression `{{}}`
fix(angular-bootstrap): make IE8 happy
fix($resource): don't use $parse for @dotted.member

params and paramDefaults support looking up the parameter value from the
data object.  The syntax for that is `@nested.property.name`.
Currently, $resource uses $parse to do this.  This is too liberal
(you can use values like `@a=b` or `@a | filter` and have it work -
which doesn't really make sense).  It also puts up a dependency on
$parse which is has restrictions to secure expressions used in
templates.  The value here, though a string, is specified in Javascript
code and shouldn't have those restrictions.
fix(ngIf): don't create multiple elements when changing from a truthy to another thruthy value.

Fixes #4852.
fix(grunt): Fix NG_VERSION_MINOR typo
fix($compile): correctly handle interpolated style in replace templates

A directive with a template with `replace: true` and an interpolated style at the root element should work correctly.

Closes #4882.
fix(urlUtils): urlUtils doesn't return right path for file:// on win

Chrome and other browsers on Windows often
append the drive name to the pathname,
as described in #4680. This would cause
the location service to browse to odd
URLs, such as /C:/myfile.html,
when opening apps using file://.

Fixes  #4680
docs(ngdoc): fix version picker grouping

The grouping of the different versions was not correct for the new 1.2.0+ releases.
Now versions are marked as stable only if they have an even number it the minor version
position (e.g. 1.0.8, 1.2.1, 1.2.0-abcde) and they are not an RC version, (e.g. 1.0.0rc3,
1.2.0-rc2).
