[WebMacro-user] patches to avoid FastWriter creation

[Alex Twisleton-Wykeham-F. <al...@fi...>]

All,

here are the patched files to avoid unrequired FastWriter creation during 
template evaluation.

Changes:-

- Template
added in a write(FastWriter,Context) method.  This is already present in the 
only implementing class (WMTemplate) so it has no affect other than exposing 
the API to classes that evaluate against the interface.

- IncludeDirective
- EvalDirective
Don't pre-cache the results of the sub-template parsing in a String but 
instead get them to write directly out to the FastWriter that is passed into 
the method.  This avoids the creation of a FastWriter to handle the template 
evaluation that is not required and which was taking up a load of processing 
time.
