| SciTE Lua scripting of edit and output panes using Scintilla API

# Scintilla API calls

Both the edit and output panes are Scintilla controls and can be scripted using Scintilla's API.

The API is presented here as it is called from Lua for the edit pane. All of the same features are available for the output pane by substituting 'output' for 'editor'.

In Lua methods are called with the ':' operator and properties accessed with the '.' operator. Properties are both readable and writeable by default and are otherwise marked "read-only" or "write-only".

The 'position' and 'line' types are integer types that represent positions and line numbers in the document. On 32-bit systems the maximum value is 2,147,483,647 but on 64-bit systems larger values are possible.

The 'pointer' type is a memory address. It is difficult to use this type from Lua but its possible it could be passed back to Scintilla or to an extension written in C.
