(doc) Adds guide for removing players from the page

[brycefisher]

Added a guide to explain how to safely remove players from the page.

Ran into a situation like this:

I couldn't find this info anywhere in the guides or documentation, so thought I'd chip in :-)

LGTM. @mmcc?

I'd probably suggest just removing this bit altogether. Any time you remove a player from the DOM (or hide it, or just don't need it anymore), it's a good idea to remove it, even if just from a resource management perspective.

Looks great! The only other thing I'd suggest is adding a section about hiding / showing a player. For instance, if you've got a modal that a player pops up in, you should create and dispose the player when the player shows / hides. If the Flash tech is used and you try to hide it, things will go poorly because, Flash.

Thanks for the PR!

Thanks for the extra info! I'll update the branch with your feedback.

If this looks good to you @gkatsev and @mmcc, I'll squash this down into a single commit in a new PR

[gkatsev]

Probably no need, since we squash it up during out merge process.

okey-dokey!

Woot! Thanks for accepting my PR @mmcc and @gkatsev
