implemented <EE> and <^E> commands for configuring encodings and translating between glyph and byte offsets (refs #5)

* ^E is heavily overloaded and can also be used to check whether a given index is valid
  (as it is the same that most movement commands to internally).
  Besides that, it is mainly useful for interfacing with Scintilla messages.
* EE takes a code page or 0 for ANSI/ASCII.
  Currently all documents and new registers are UTF-8.
  There will have to be some kind of codepage inheritance and a single-byte-only mode.
