58b7800172 Migrate most uses of the Span concept to Tag
Also migrate mv, rm and commands like that to taking a
SyntaxType::Pattern instead of a SyntaxType::Path for their first
argument.

8a29c9e6ab Migrated numerics to BigInt/BigDecimal
This commit migrates Value's numeric types to BigInt and BigDecimal. The
basic idea is that overflow errors aren't great in a shell environment,
and not really necessary.

The main immediate consequence is that new errors can occur when
serializing Nu values to other formats. You can see this in changes to
the various serialization formats (JSON, TOML, etc.). There's a new
`CoerceInto` trait that uses the `ToPrimitive` trait from `num_traits`
to attempt to coerce a `BigNum` or `BigDecimal` into a target type, and
produces a `RangeError` (kind of `ShellError`) if the coercion fails.

Another possible future consequence is that certain performance-critical
numeric operations might be too slow. If that happens, we can introduce
specialized numeric types to help improve the performance of those
situations, based on the real-world experience.

ca0c6eaf58 This commit introduces a basic help feature. We can go to it
with the `help` command to explore and list all commands available.

Enter will also try to see if the location to be entered is an existing
Nu command, if it is it will let you inspect the command under `help`.

This provides baseline needed so we can iterate on it.

138b5af82b Basic support for decimal numbers
This commit is more substantial than it looks: there was basically no
real support for decimals before, and that impacted values all the way
through.

I also made Size contain a decimal instead of an integer (`1.6kb` is a
reasonable thing to type), which impacted a bunch of code.

The biggest impact of this commit is that it creates many more possible
ways for valid nu types to fail to serialize as toml, json, etc. which
typically can't support the full range of Decimal (or Bigint, which I
also think we should support). This commit makes to-toml fallible, and a
similar effort is necessary for the rest of the serializations.

We also need to figure out how to clearly communicate to users what has
happened, but failing to serialize to toml seems clearly superior to me
than weird errors in basic math operations.
