[VELOCITY-264] Escaping in form of "$\!{foo}" does not work

Description

Below are the results of executing app_example1 with a modified "example.vm"
file. The content of the example.vm is a copy-paste from Velocity Userâ??s Guide
(see the URL). Note that "$!

{foo}" was rendered to "$Unable to render embedded object: File ({", instead of "$) not found.{foo}

"
as expected:

D:\dev\velocity-1.4\examples\app_example1>type example.vm
#set( $foo = "bar" )
$!foo
$!

{foo}

$
!foo
$\\\!foo

D:\dev\velocity-1.4\examples\app_example1>example
Using classpath: .;..\..\bin\velocity-1.4.jar;..\..\bin\velocity-dep-1.4.jar
$!foo
$!{
$!foo
$
!foo
D:\dev\velocity-1.4\examples\app_example1>

Surprisingly, I could really use this feature as I want to evaluate my
template in two steps: cache the result of the first generic step and then
reuse it to generate various final messages.
