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.
