Drop #!feature(specialization) in favor of having a `cli`
property for types to decide whether they are CLI
compatible.
The unconstrained_type! macro now has both ParseCli and
ParseCliFromStr in view, and requires one of the two to be
implemented for a type. This means that if a type implements
FromStr, it should "just work".
For types created without the help of the #[api] macro,
there's a shortcut to exclude a type from the CLI via
the no_cli_type!{typename} macro.

In order to get parameters from the command line into the
API we need to get them into a json value, so that we can
pass it down the handler which deserializes them into their
real type and runs verifications.
For this we need to define how the type is going to be
converted into a json Value. We cannot simply use
Deserialize as that would for instance require quotes
around strings. So instead, we have a ParseCli trait, which
is a nop (direct serde_json::Value::String()) for string
types, and uses .parse() (the std::str::FromStr trait) for
everything else.
Currently this uses a `default fn` as an example of the
specialization feature, but I'll probably remove this and
use yet another mass-impl macro since there isn't much
activity on that feature's issue tracker. (The issue itself
seems to be outdated ...

while filling the Parameter fields as &'static we cannot
really make use of the get_type_info() yet because it would
need to be a `const fn` (possible via #!feature(const_fn)),
so for now we store the method pointer until `const_fn` is
stable

This should support arbitrary expresion, so gobble up
elements up to the next comma and then run it through
syn::parse2.

TODO:
- change parse_object to use Punctuated for the fields to
support longer value types (so we can use actual types
as fields)
- allow adding a body type to methods
- allow adding a body type to routers explicitly
