Henrik Ingo 713557d4d2 Add mouse-timeout plugin
This commit adds a generic mouse-timeout plugin. (Same code was
originally part of toolbar plugin, but is now general purpose and
available to user to apply any CSS to it.)

Although this implementation is different and more generic, the
suggestion to add ability to hide mouse cursor came from
a pull request by Sebastian Clausen (@sclausen):
impress#536

The functionality is simple:

After 3 seconds of mouse inactivity, add the css class
`body.impress-mouse-timeout`. On `mousemove`, `click` or `touch`, remove the
class.

A user will then use (or not) his own CSS to hide whatever he wants to hide
after 3 seconds of mouse inactivity.

Mouse timeout plugin

After 3 seconds of mouse inactivity, add the css class body.impress-mouse-timeout. On mousemove, click or touch, remove the class.

The use case for this plugin is to use CSS to hide elements from the screen and only make them visible when the mouse is moved. Examples where this might be used are: the toolbar from the toolbar plugin, and the mouse cursor itself.

Example CSS

body.impress-mouse-timeout {
    cursor: none;
}
body.impress-mouse-timeout div#impress-toolbar {
    display: none;
}
