Breaking changes

Don't special case u64 by @SergioBenitez

If you are using a u64 in your struct to get the number of occurence of a flag, you should now add parse(from_occurrences) on the flag.

For example

#[clap(short = "v", long = "verbose")]
verbose: u64,

must be changed by

#[clap(short = "v", long = "verbose", parse(from_occurrences))]
verbose: u64,

This feature was surprising as shown in #30. Using the parse feature seems much more natural.

Change the signature of Structopt::from_clap to take its argument by reference by @TeXitoi

There was no reason to take the argument by value. Most of the StructOpt users will not be impacted by this change. If you are using StructOpt::from_clap, just add a & before the argument.

Fail if attributes are not used by @TeXitoi

StructOpt was quite fuzzy in its attribute parsing: it was only searching for interresting things, e. g. something like #[clap(foo(bar))] was accepted but not used. It now fails the compilation.

You should have nothing to do here. This breaking change may highlight some missuse that can be bugs.

In future versions, if there is cases that are not highlighed, they will be considerated as bugs, not breaking changes.

Use raw() wrapping instead of _raw suffixing by @TeXitoi

The syntax of raw attributes is changed to improve the syntax.

You have to change foo_raw = "bar", baz_raw = "foo" by raw(foo = "bar", baz = "foo") or raw(foo = "bar"), raw(baz = "foo").
