Also add script for generating the PNGs and add pre-rendered PNGs
for the Linux electron build which means you don't need icns2png
to build it and the Linux icons are straight from the SVG rather
than resized bitmaps.
which it turns out is by far the lesser of two evils.
* Auto-update works with a proxy
* The update process is reasonably atomic & faster, rather than
running the uninstaller then the installer, leaving you with a
broken install if you shut down your machine at the wrong time
* Gets the update URL the same way as on mac, rather than baking
it into the app at build time from package.json. We don't want
it in package.json because only our builds want our update URL.
Amalgamate the electron build packaging into one script.
Use update_base_url so we can compute the actual URL in the
script for windows (because we need to put it in the build) and
at runtime for mac os.
* Remove the config: nobody else wants our update URL so we'll
keep it separately. Don't copy the config.
* Script to yell at you if you've build a package with auto
update turned off.
* s/vector/webapp/ when looking for config
* Use different update URLs for the various platforms
We are now using `cpx` to copy the emojione files, so we might as well use it
for olm.js, rather than rolling our own - particularly since that makes it easy
to add a watcher for `npm start`.
We have to add a `-L` to the `cpx` invocation, otherwise, if olm is a
symlink (as is useful for development), cpx ends up watching the symlink, which
obviously never changes.
