Cut the tilemenu script into smaller pieces, one script for each tab, handling displaying and clearing their content. Did a lot of changes on the menu prefab. Simplified it a lot but also changed how it looks a lot.

TODO

• [x] Separate code in multiple script, one for each tab (build, remove, save, load)
• [x] Add a ITileMenuTab interface with method refresh and method show, implemented by all scripts above.
• [x] Refresh content upon clicking a tab.
• [x] Do not change map name if a map is already named like the string entered
• [x] Add renaming map.
• [x] Maybe inherit from input field so they automatically handle toggling off controls (because they should all do that and there's multiple)
• [x] Add an enum, for all tabs in the menu, so TileMapMenu knows which tab to refresh and load when clicking on a tab, and which one is currently showing.
• [x] integrate search bar, layer selection dropdown and build or delete button into the content area of the build tab.
• [x] Capture input when renaming.
• [x] Change display of renaming input while renaming.
• [ ] try to fix the "commit" input issue of the renaming when the controls are staying off.

Known issue

• pressing enter when changing the name of a map does not restore control to player. I can't figure out which event should trigger when pressing enter, I've tried a lot of different things. I posted an question here. https://forum.unity.com/threads/which-event-or-method-is-raised-in-tmp-input-fields-when-pressing-enter.1524796/

@cosmiccoincidence will change the color. The client was not able to load the map before. I guess we can add later that functionnality if we need to. Won't be too hard, just a call to the server and checking rights of the client.
