Fix paragraph selection corner case; modules/textadept/editing.lua
The buffer API applies to all buffers now, not just the global one.
Created a "dummy" Scintilla view for operating on non-global documents.
Removed `buffer:check_global()` and replaced `buffer.dirty` with Scintilla's
`buffer.modify`.
Added "Save All" to the menu.
Fixed corner case bug in block uncommenting; modules/textadept/editing.lua
The caret is always constrained to the first line when no selection is present.
