Improve deployment process for shiny apps

[mitchelloharawild]

Shiny apps and other services require the icons cached. As the downloading process may take substantial time, this downloading should only happen once per server.

Some tools for easily deploying apps with icons would be helpful.

A vignette would be a good start for this. More sophisticated methods can be added in later versions.

Added icon_save() for saving icons locally within a project. A vignette would be useful, but the examples are sufficient for now.

Another option could be setting icon_self_contained("icon_dir"), which adds icons to this directory from the installation path if they don't already exist there. This way the set of required icons does not need to be thought out before using them (or needing to add the needed icons in multiple locations of the code).
