All of those cpx invocations were getting unwieldy, and I suspect the exotic
quoting needed to run them under parallelshell was breaking things on windows.
Replace the unwieldy cpx invocations with an unwieldy custom script.
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 squirrel hooks (the installing & uninstalling is now
done by the, er, installer)
* Switch to electron-auto-update
* Shorten initial update delay because we no longer need to wait
for squirrel to release a lock file
* Change update URLs because windows is now one installer for
both 32 & 64 bit.
* Update electron-builder to 10 where NSIS is now the default
target for Windows.
* Add linux to the target list, building a deb.
* Remove sqirrel-specific installation spinner
* Remove redundant !**/* from files
* Implement the squirrel install / uninstall hooks (so we have
a start menu entry / desktop shortcut)
* Wait longer before checking for update
* Set the window icon
* Add a 'file' menu
* Bump electron-builder
* Add the icon url for the control panel entry
Advantages:
* blocks while a rebuild is in progress so you're less likely to reload the
old version
* serves from memory rather than disk, so we no longer need to turn off the
cachebuster to avoid filling the disk with bundles. Empirically, seems to
last a plausible amount of time without OOMing; there's no real reason to
believe it would use any more memory than webpack itself.
* That in turn means we no longer need the hack to stop chrome caching old
sourcemaps (because the sourcemap now has a cachebuster in its name).
* one fewer process for parallelshell to (fail to) manage.
* in future, we could consider the fancy hot-reload functionality.
