Proper (de)serialization format handling.
For a while Chrono's serialization support was barely working, i.e. usable but never been safe. While it wouldn't cause any memory unsafety, attacker can fabricate an input that will make most users confused (e.g. seemingly same Date which doesn't compare equally). This commit will properly error for those cases. It was also problematic that the generated rustc-serialize format is very inefficient, especially for JSON. Due to the backward compatibillity this commit does NOT fix them (likely to be in 0.3), but this does try to define the exact format and define tons of tests to detect any change to the serialization. There are several remaining problems in the serialization format; the serde implementation seems good, but it is unable to distinguish some cases of leap seconds (practically won't matter, but still). The rustc-serialize implementation would require a massive redesign. For now, I postpone those issues to 0.3 (what a convenient excuse). Fixes #42.
