chore(*): Upgrade Crates, Increase version to 0.10

[jolhoeft]

regex 0.1 -> 0.2
mustache 0.6 -> 0.8
hyper 0.9 -> 0.10
lazy_static 0.1 -> 0.2
compiletest_rs 0.1 -> 0.2

Note: since hyper removed ssl support, nickel no longer has it

The CI failures are due to #399, and are not affecting the working of nickel. They are currently just warnings about a deprecated feature. I am going to merge, and then see about address #399.
