Adds possibility to build extension files (Chrome and Safari) from
command line.
To run from the project directory:
python tools/build.py [meta]
If the optional `meta` argument is set, then only the manifest and
language files are uptated.
Without that everything is being built (extension files too) into the
`dist/build/version_number` folder.
For Chrome there will be two files, a crx, and a .zip file which
includes the key.pem private key (so this must not be shared,
it's just a bit help for publishing it to the Chrome Web Store).
Beside the extension files, update-files are generated too (for self
hosting - Safari needs it).
It works similarly to the xhr intercepting, except here the window.open
global function is being overridden.
Note that it could only work if the site's Content Security Policy allows
inline scripts, and the script on the webpage doesn't have a copy of the
original window.open function (it can happen only if the page has an
inline script in its head element, where the reference to the original
function can be obtained - likely this cannot be prevented in Safari).
Benefits:
- Cross browser solution (however only for relatively new browsers)
- Doesn't need extra permission in Chrome
If the browser doesn't suppor the download attribute, then a new tab will
be opened with the exported data.
Other changes:
- Start the download only if the data is not empty (previously the
download started anyway)
- Reorder code in vapi-client.js for Safari, so unnecessary code doesn't
run on extension pages
