Add file hash to blueice hash

[hammannr]

So far, if you made changes to a template that was already cached by blueice, blueice would use the cached version instead of the new one. This PR solves this issue by computing the hash of each source's template file and adding it to the blueice source config.

I checked that it works but quickly want to add a unittest and do a few more checks tomorrow.

But if you already have any code-related suggestions @dachengx please let me know 😊

Ohhh ok nvm -- it kills some unittests, I'll fix it tomorrow..
