Rearrange the file layout in preparation of becoming a monorepo

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

-configuration is necessary.

-                          EscapeOneShot);
-
-void setup () {
-  Kaleidoscope.setup ();
-}
-```
-
-The plugin only makes sense when using one-shot keys.
-
-## Plugin methods
-
-The plugin provides the `EscapeOneShot` object, which has no public methods.

-## Dependencies
