Title: Implementing search feature in map choosers

ref #6374
I've implemented this filter. It looks that it integrates with whole code without disturbing any coherency.. Please share me any thoughts.

My objection in MapChooserLogic.cs:91
```
.Where(m => m.Type == gameMode || gameMode == null)
```
-> the null check was at right (left side is being checked first in logical alternative) so I've moved it to left, and checked this null case - its handling it right now.
