increased character limits

on most text based inputs, the character limit overall should be increased (especially for the UI text action for the counter block or whatever its called), and stuff like color tags or text formatting shouldn't count toward the character limit.

Start by locating the character-limit handling for text-based inputs, especially the UI text action used by the counter block. Check how color tags and text formatting are included in the current count. Done means the agreed higher limits apply consistently and formatting markup no longer consumes the user-visible character allowance.
