fix issue 114

[jsnyders]

I believe this is one way to fix the issue 114. When a <% %> template was used as a dictionary value the %'s were not being stripped.
I tested the change with this group template

delimiters "$","$"
d1 ::= [
  "p": <%hi%>
]
main() ::= <<$d1.p$>>

and the problem was fixed (expected result hi was returned).

Fixes #114

I think you have the right idea for a solution. Do you mind adding a test to help prevent future regressions? My suggestion would be to place it here, and include a comment like this so everyone knows it was added for a specific reason. If you have any questions, or if you don't have time and wish for one of the other authors to create the test instead, please let us know. 😄

❗ You'll need to add your name to contributors.txt before we can accept code contributions. Note that this is a one-time thing. If you prefer, you can add your name to the ANTLR 4 contributors list instead, which will cover StringTemplate as well as other projects in the ANTLR organization.

I will add a test case. My Java skills are rusty. I have to remember how to run jUnit tests.
I will add my name to contributors.txt

I added a test case and updated contributors.txt in the same commit. Let me know if I didn't do it correctly.
It would be helpful if the ant script had a target for building and running the tests but I figured it out.

thanks! Sorry it took so long ;)
