[Quest API] Add Popup methods to Perl/Lua. (#2533)

* [Quest API] Add Popup methods to Perl/Lua.

# Perl
- Add `quest::popupcentermessage(message)` to Perl.
- Add `quest::popupcolormessage(color, message)` to Perl.
- Add `quest::popupindent()` to Perl.
- Add `quest::popuplink(link)` to Perl.
- Add `quest::popuplink(link, message)` to Perl.

# Lua
- Add `eq.popup(title, message)` to Lua.
- Add `eq.popup(title, message, popup_id)` to Lua.
- Add `eq.popup(title, message, popup_id, buttons)` to Lua.
- Add `eq.popup_center_message(message)` to Lua.
- Add `eq.popup_color_message(color, message)` to Lua.
- Add `eq.popup_indent()` to Lua.
- Add `eq.popup_link(link)` to Lua.
- Add `eq.popup_link(link, message)` to Lua.

# Notes
- Adds the Perl plugins like PWAutoCenter, PWIndent, and PWHyperlink.
- Parses out HTML `<>` tags automatically in `popupautocenter` to properly center stuff like colored messages. (Doesn't work with links)
- This lets Lua users have similar functionality to Perl users.

* Add tables and break.

* Add indent_count to indent method.

* Move to Dialogue Window.
