Surround's "all line" surrounds non-whitespace.

Any trailing whitespace is ignored.

Renamed textobject seeing how it *doesn't* select a full line.
Move InnerLineTextObject to Vrapper Core.

There can be other (though rare) plugins which might benefit from it.
Feature: add textobj-line port.

This plugin will map two textobjects: 'al' for textrange 0 to end-of-
line (exclusive) and 'il' for the first non-whitespace char to the last
non-whitespace character of the line (inclusive).
