1473fccceb Make website/ its own Go module. 
This allows us to remove toml as a dependency of the src.elv.sh module since it
is only used in the website's building process.

Introduce the path: module (#1203) 
* Introduce the `path:` module

This is based on https://github.com/elves/elvish/pull/1084 by @kolbycrouch
submitted five months ago. It addresses all of the feedback on that
change and includes other documentation and unit test improvements. It
also includes a couple of extensions to the original P.R., such as a
`path:is-abs` command.

I decided to resurrect that change because I want better support for
filesystem path manipulation so that users can replace non-portable
external commands such as `realpath` and `find` with Elvish builtins. This
is a baby step towards that goal.

Related #849

* Add a `path:is-regular` command

This adds a `path:is-regular` command.  This is for symmetry with the
`path:is-dir` command and the glob `[type:regular]` modifier.

It also adds support for symlinks in the `testutil.Applydir` function
and change the path unit test to use it.

* Rename path:real to path:eval-symlinks

072677351b Introduce "var" and "set". 
Assignment using "foo = bar" instead of "var foo = bar" or "set foo = bar" is
not yet deprecated, but will be soon.

This addresses #645.

d52aa03764 In prompts implicitly coerce float64 to string 
Including the float64 data type in the prompt value stream causes an error.
This causes those values to be implicitly converted to a string as happens
everywhere else in Elvish.

I initially intended to modify the code to do the implicit string coercion
for any type not otherwise explicitly handled by the pkg/ui `Concat`
methods. I decided against that approach because doing so doesn't make
sense for some types that might appear in the value stream; e.g., Elvish
exceptions.

Fixes #1186

9edcb78050 Make key binding syntax more consistent 
Document the format key of names and modifiers; albeit with a TODO
regarding the `Shift` modifier.

Make function key modifier matching case sensitive (`Alt` not `alt`)
to match key name matching (`Enter` not `enter`).

Implement `Ctrl-?` as the logical counterpart to `"\c?"`.

Resolves #1163

784c4159d2 Minor documentation improvements 
Fixing issue #857 will require some non-trivial work. But I noticed these
documentation cleanups when I started working on the issue so I'm making
them as an independent change.
