* moves login button to top-left
* switches from iframe to a request() to load the welcome page to inherit CSS (probably breaks RTS :/)
* namespace CSS
* change the layout a bit.
* Move language files to strings/ subdir to be consistent with
react-sdk
* Only copy static list of languages (to avoid including
languages that are only a few percent translated)
* Make copy-res script work with watch mode
* Other general cleanups like only write each language file once,
rather than n times.
This uses the github.com:googlei18n/region-flags and imagemagick to generate 27x27 flag pngs. The flags have a 1px #e0e0e0 border and transparent padding such that each flag is of the same height (17px including the border).
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.
