Add URL query variable to display a client-side marker

[iperrealistico]

Add a query to be optionally used at the end of the url to place a marker (Dynmap and Pl3xmap) only on the client-side.

This means that the marker wouldn't be actually created, but just seen by the user using that URL.

Example:

Before https://www.peacefulvanilla.club/maps/#World;flat;3591,64,-3442;7

After https://www.peacefulvanilla.club/maps/#World;flat;3591,64,-3442;7#placeMarker=true&type=pin&name=Map_Art

that would display a pin marker named Map Art at that location

This would be a very nice feature, to connect our wiki with the online map.

This is very unspecific. Yes, we could add an IFrame to the wiki page, but the pin is still missing.
