Bug 148771

This is in response to a thread on the nbdev list
(http://www.netbeans.org/servlets/BrowseList?list=nbdev&by=thread&from=875497).  

Consider the following scenario:

1.  User sees that the File-> New Java Class template has tokens like ${package} and ${name}.  These are replaced at the
time of file creation with their corresponding values (in this case, the package and name of the newly created class).

2.  User wants to create a custom template, for example, for a specific type of Java class and so he creates a source
file with these same tokens.

3.  User right-clicks on the source file's node, chooses "Save As Template" and then saves it into the desired category
(e.g. "Java")

4.  User goes to File -> New File, selects the "Java" category and chooses the template from the previous step.

5.  User specifies the name and location of the file to create and clicks "Finish"

6.  User finds that the tokens are not replaced as expected.  The source file created from the template contains literal
${package} and ${name} instead of having those tokens replaced with the new class' package and name as was done for the
Java source file described in step 1.

The only workaround that I know of involves writing a module that will set the "javax.script.ScriptEngine" attribute to
"freemarker" on the template's FileObject in the system filesystem.  However, it is unreasonable to expect someone who
is merely using the IDE to have to do this.  Therefore, I think the IDE should have some user interface for marking a
template as a freemarker template.

I have written a very simple action which lets you do this and will attach it to this issue momentarily.  It is intended
more as a proof-of-concept than an actual implementation, since the actual implementation could be as simple as a new
action on the existing template node.
