Add setting to represent languages as labels instead of flags in backend.

[hatsumatsu]

This is a rough PR for adding text based language labels in the WP backend. To test this feature go to Settings > Multisite Language Switcher and set Admin Display to Labels.

The labels are displayed in post lists, post edit screens and in the admin bar. See attached screenshot.

@lloc - Both this PR and #150 are trying to address a common goal where the default country/flag doesn't fit.

Examples include:

• The en_CA and fr_CA flag are identical.
• A network has multiple pairs of sites (10 sites = 5 actual sites x 2 language each) and having the identical flag for selector.

Would be good to know if these approaches are enhancements likely to be considered?

I agree that this is probably the way to go ... I'd like to be sure that the user can choose which solution is the best for his/her needs. I did not check this but I will do this as fast as possible.

Thanks. Running a fork with PR150 in some environments until the chosen/preferred approach gets implemented. Would love to be able to return back to master with WP 5.8+ if that kind of time frame is realistic for one or other to be part of plugin updates?

Hi @lloc , no pressure, but just curious if you consider this PR to be a good idea and potentially being merged? Would love to see this feature in the official version of the plugin :-)
