Handle unknown CSI events and bracketed pasted in the terminal version.
For bracketed paste, turn off auto-pair and auto-indent.
Enable mouse clicks and movements in the terminal version.
This requires Scinterm r92 (changset 90ba2dd413c3).
Enable terminal mouse clicks and movements in Windows; src/textadept.c
Fixed bug in `lL_event()` for LUA_TNUMBER type size mismatches; src/textadept.c
The type extracted for LUA_TNUMBER was `sptr_t` (long), however most of the
time, `int` is used. Since `sizeof(long) > sizeof(int)`, `lL_event()` sometimes
pushed extra bytes in memory around the original integer passed (at least I
think this explains the behavior I observed).
Improvements to terminal mouse handling.
Emit events for unhandled mouse events and connect to such events in order to
focus and resize views.
Patch libtermkey with new Win32 PDCurses driver for unified key/mouse input.
Update CDK patch to always use libtermkey and to ignore mouse events.

Requires Scinterm r97 (changeset 8d1a625c9b4d).

Thanks to Chris Emerson for proof of concept code that handles mouse events and
for the code that focuses and resizes views.
Patch Scintilla to configure "closeness" of mouse clicks; src/scintilla.patch
This patch is subject to change until Neil applies or modifies the upstream
patch I sent.
