Allow escaping of '%' in templates about grasp

[karlicoss]

Hi, seems that org-mode spec suggests using \% for escaping https://orgmode.org/manual/Template-expansion.html#FOOT87
Would that suit you?

You're right, this line is responsible for template expansion https://github.com/karlicoss/grasp/blob/master/server/org_tools.py#L67 I haven't tried, but I think you'd need something like py_template = re.sub(r'[^\\]%[:]?([?\w]+)', r'{\1}', org_template), so it excludes the \% from matching.

Yes, \% would suit me perfectly

Thanks for the regex, I will try changing the python and make a pull request if I'm successful :)

I think this works now :)
