Include salve in distribution.

It is better to include salve in the distribution so that the
salve-convert that is proper to the salve with which wed was built
is readily available.
Don't install the CSS for Font Awesome and Bootstrap.
Fixed documentation typo.
Dropped validation_domlistener.

The module mutation_domlistener does not work on IE < version 11.
Longer timeout when doing remote testing.
IE does not accept `undefined` in `insertBefore`.

On Chrome and Firefox you can do `el.insertBefore(node_to_insert,
undefined)` and it will add the node to the end of `el` as if the last
argument were `null`. IE (< 11, and probably 11 too) chokes on
`undefined`.
Work around a Selenium bug.

When using IE, Selenium wraps a `ClientRect` in a WebElement. This
modification is for working around that problem.
Add the possibility to skip modules.
Optimize lodash.

Doing this shave 4.5-5s per scenario when using Sauce Labs.
Use a newer version of rangy.

1.3alpha.804 and later has support for AMD but it does not allow
optimizing (because it uses an anonymous `define`), hence the
modifications to requirejs.build.js.
Added the /forever location.

This location allows to run remote tests without having to have a back
and forth between the browser and the server to check if a resource
needs refreshing. Basically, expiry is set to 10 years in the future
for files served from this location.
Optimizations of the selenium suite.
Improve loading time of tests.
Make server slightly more responsive.
Browser updates.
Fixes for IE.
Use the element to send keys.
Removed _seekCaret.
Updated dependencies.
Don't start the validation work right away.
