fix *significant* typo Inster -> Insert

[fduncanh]

This is a significant typo.

I am using your c++ class ap_casting_media_store verbatim (with the hlsparse library) , through extern "C" wrappers to and from C, with http handlers in C that are functionally-equivalent to your handlers, and an extern "C" implementation of send_fcup_request.

The first POST /action request I see after POST /play is of Action type "playlistInsert" not "unhandledURLResponse"

Unfortunately, your code tests the Action type against "playlistInster" so misses it because of the typo (and I have no model to follow for implementing this action because it is unimplemented in your code).

• there are a number of "cosmetic" other typos (hanlder for handler, meida for media , plus others) that I noticed. Would you like a Pull Request to fix these?

• any suggestions on handling these unhandled action types playlistInsert and playlistRemove?

Thank you for correcting my fat finger
