Allow views to be used as buffers and update API.

This allows for a superficial separation of buffer- and view-specific Scintilla
functionality. buffers and views can now be used interchangeably for the most
part, and the APIs are guidance, not hard requirements. User scripts do not
require any modification and will continue to function normally.

+#### View API Additions and Buffer API Changes
+
+Textadept's [buffer][] API is largely based on the [Scintilla API][], which does
+not distinguish between buffer- and view-specific functionality. Textadept 11
+now attempts to separate this functionality, but only superficially. Buffers and
+views may be used interchangeably for the most part, but the [buffer][] and
+[view][] API provides _guidance_ (not hard requirements) on which functions and
+fields are more appropriate for their respective objects. _User scripts do not
+need to be updated and will continue to function normally_. The following "Find"
+regex can be used to help convert `buffer.*` functionality to `view.*`:
