Fix issues with parsing nested tags

[mrubens]

Trying to fix the issue in cline#832 - still not working though, I think because of how it gradually builds up the response and tries to parse it as it goes.

Prolly need to add a build step to prepend a short string to every tool invocation so that what is in the source is not what cline is actually looking for at runtime.
just everywhere in the prompt & parsing code replace say the raw '' string with '<{pre}-write>' where pre could be set = 'roo'
