Update to 1.0.10, fix travis (#31)

* Update to OpenVR 1.0.10

* Typo fix

* Missing doc comment

* Delete dead examples, cleanup

* Delete dead code

* Remove lifetimes from subsystems

OpenVR must be shut down manually, which invalidates outstanding
subsystem handles regardless of lifetimes, rendering the ergonomic
sacrifice pointless.

Future work: make shutdown safe by inserting checks before every
OpenVR call.

* Depend on our own openvr-sys

* Update metadata

* Update readme

* More detailed safety notes

* Depend on released openvr-sys
