add window:set_config_overrides lua method This commit expands on the prior commits to introduce the concept of per-window configuration overrides. Each TermWindow maintains json compatible object value holding a map of config key -> config value overrides. When the window notices that the config has changed, the config file is loaded, the CLI overrides (if any) are applied, and then finally the per-window overrides, before attempting to coerce the resultant lua value into a Config object. This mechanism has some important constraints: * Only data can be assigned to the overrides. Closures or special lua userdata object handles are not permitted. This is because the lifetime of those objects is tied to the lua context in which they were parsed, which doesn't really exist in the context of the window. * Only simple keys are supported for the per-window overrides. That means that trying to override a very specific field of a deeply structured value (eg: something like `font_rules[1].italic = false` isn't able to be expressed in this scheme. Instead, you would need to assign the entire `font_rules` key. I don't anticipate this being a common desire at this time; if more advance manipulations are required, then I have some thoughts on an event where arbitrary lua modifications can be applied. The implementation details are fairly straight-forward, but in testing the two examplary use cases I noticed that some hangovers from supporting overrides for a couple of font related options meant that the window-specific config wasn't being honored. I've removed the code that handled those overrides in favor of the newer more general CLI option override support, and threaded the config through to the font code. closes: #469 closes: #329 2021-02-28 01:53:19 +03:00			# `window:get_config_overrides()`
