Fixes based on the previous release.

Time trial mode and local record recording enabled.

Various lobby fixes.

Complete music pipeline: menu → pre-race → race → results. The initial batch of music was generated to approximate the desired vibe.

Texture filtering for normal/specular maps reverted to anisotropic.

Pause menu separated from the main menu.

Pit lane: First iteration; vehicles start with enough fuel for 3 laps. In longer races, pitting is required to refuel. Vehicles also sustain damage, which can be repaired in the pits.
