Rearrange the file layout in preparation of becoming a monorepo

Move the documentation to `doc/plugin/LED-ActiveModColor.md`, sources under
`src/kaleidoscope/plugin/` (appropriately namespaced). This is in preparation of
merging plugins into a single monorepo.

-With this plugin, any active modifier on the keyboard will have the LED under it
-highlighted. No matter how the modifier got activated (a key press, a macro,
-anything else), the coloring will apply. Layer keys, be them layer toggles,
-momentary switches, or one-shot layer keys count as modifiers as far as the
-plugin is concerned.
-
-## Using the plugin
-
-To use the plugin, one needs to include the header, and activate the effect. It
-is also possible to use a custom color instead of the white default.
-
-```c++
-#include <Kaleidoscope.h>
-#include <Kaleidoscope-LEDControl.h>
-#include <Kaleidoscope-LED-ActiveModColor.h>
-
-KALEIDOSCOPE_INIT_PLUGINS(LEDControl,
-                          ActiveModColorEffect);
-
-void setup () {
-  Kaleidoscope.setup ();
-
-  ActiveModColorEffect.highlight_color = CRGB(0x00, 0xff, 0xff);
-}
-```
-
-It is recommended to place the activation (the `KALEIDOSCOPE_INIT_PLUGINS` parameter) of the
-plugin last, so that it can reliably override any other plugins that may work
-with the LEDs, and apply the highlight over those.
-
-## Plugin properties
-
-The plugin provides the `ActiveModColorEffect` object, which has the following
-properties:
-
-### `.highlight_color`
-
-> The color to use for highlighting the modifiers. Defaults to a white color.
-
-### `.sticky_color`
-
-> The color to use for highlighting one-shot modifiers when they are sticky. Defaults to a red color.
-
-## Dependencies
-
-* [Kaleidoscope-LEDControl](https://github.com/keyboardio/Kaleidoscope-LEDControl)
-* [Kaleidoscope-OneShot](https://github.com/keyboardio/Kaleidoscope-OneShot)
-
-## Further reading
-
-Starting from the [example][plugin:example] is the recommended way of getting
-started with the plugin.
