Feature Request: Line wrap on chained method calls

[trustytrojan]

It would be really nice to have a setting that enforces this style of line wrap on the method call operator :, using continuation_indent to indent the wrapped lines.

-- before
self:xy(PB.list_center_x, PB.list_center_y):zoomto(PB.list_width, PB.desc_box_height):diffuse(color('#1a1a1a'))

-- after
self:xy(PB.list_center_x, PB.list_center_y)
	:zoomto(PB.list_width, PB.desc_box_height)
	:diffuse(color('#1a1a1a'))

Currently, it only wraps the right-most token that breaks the line width constraint to the next line:

-- after (current behavior)
self:xy(PB.list_center_x, PB.list_center_y):zoomto(PB.list_width, PB.desc_box_height):diffuse(color(
'#1a1a1a'))

This project is missing some behaviors that proactively wrap chained expressions and is unlikely to change for a long time. I hope to add these features when I have time to rewrite it in Rust.
