	Refactor headers

	slackline_internals.h:
	contains common operations for the `slackline` struct not meant to be used
	outside of slackline.

	slackline.h:
	contains the API for slackline. The `slackline` struct may become opaque
	in the future.

	Diffstat:
	M slackline.h \| 6 ++++--
	A slackline_internals.h \| 14 ++++++++++++++
