Get things in place for a color scheme setting.

[trey]

I think this is close if I knew how to create a database migration. :)

Issue #627

@heyitsal @spaceninja What do you think? Should this be a "color scheme" account setting, or should it be a "Theme" account setting? I think the latter allows for eventual alternate themes beyond light/dark/"default" selections.

@trey In addition to creating a database migration, you'll need to update the setup/db-install.sql and setup/db-fixtures.sql files. Those are used to create an initial database structure for tests and for local development. All of the migrations are "applied" from running those two scripts (since db-install.sql represents the current schema, any schema changes should be made there also).

Feel free to document this for the project README file. I mention how to apply any migrations against a local instance, but now how to develop one.

I said "color scheme" in the issue, but I don't have any particularly strong feelings about it. I'd be fine with calling it "Theme"

I don't know Python, but think this is what you mean?

Suggested change

	<html{% if current_user_object and current_user_object != 'match' %} class="{{ current_user_object.color_scheme }}"{% end %}>
	<html{% if current_user_object and current_user_object.color_scheme != 'match' %} class="{{ current_user_object.color_scheme }}"{% end %}>

Thanks for starting this!

The macOS setting is labelled "Appearance".
