* mmol/L wording tweak in Readme
* Various wording & clarity tweaks in the Readme
* Heroku template update to reflect mmol allowance tweak
* Update README.md

Ran some proper browser test suites, determined actual minimum specs for the main site.

* need to fix my md error
* Update CONTRIBUTING.md
Few more tweaks
* Update CONTRIBUTING.md
* Update CONTRIBUTING.md
* Update README.md
Change Discord URL to be an invite link instead of a direct link to the channel (which doesn't work if you're not already in it).
* Rewording the "store hash" label
(Nobody in the public knows what a "hash" is; this setting is constantly misunderstood.)
* Update languge.js to match
This modal dialog about converting the profile to a format that 0.9.0 or earlier won't support is still popping on fresh installs, shouldn't be required at this point.
* Remove Profile Editor toggle
`profile` isn't an optional plugin anymore; doesn't need this display toggle. (Plus it was erroneously toggling off in the absence of the `basal` plugin — see #4442.)
* Remove profilecontrol class
Didn't get any feedback either way on this change after multiple enquiries, so going ahead with simplification here. If anyone sorely misses any of these items from the default form, can always put them back in. Also added SHOW_PLUGINS, as it's a useful starter setting.
* Update simple clock scaling
Brings clock.html in line with clock-color.html, in terms of proper viewport scaling. Also adds "minutes ago" text on stale data, which I think is appropriate even in this stripped-down view.
* Fix bgclock scaling
Bring bgclock.html in line with the other clock views, in terms of proper viewport scaling.
* fix typo
