Use another HTML tag instead of script - new property "templateTag"

[jakub-gawryl]

In one of my projects i cannot use "script" HTML tag to contain templates, so i think it'll be good idea to add new property eg. "templateTag" where you can define which HTML tag you use to keep templates.
Of course i bypassed this small issue without problems, but it'll be great feature for all i think.

If you wish to create a pull request to support this, I am happy to add it in. You can also use external templates as an alternative.
