Add reconnect button to disconnection notice. (#1102)

* Add reconnect button to disconnection notice.

Reads and begins the connection process to the last server the user disconnected from. Doesn't complete the connection process.. yet.

* clang formatting

* Remove class from debug_functions, add prompt into AoApplication instead.

Co-Authored-By: Leifa <26681464+TrickyLeifa@users.noreply.github.com>

* clang formatting 2

* clang formatting 3

* clang formatting 4

* Complete connection process

Reconnects to last server fully. Sends to character select screen.

* Add disconnection

* Delete comments, unused class
