Velgress VS Mode Release (v1.12)

Adds a range of new options and improvements for Velgress:

• Separate character sprites for each player
• Starting powerups can be selected in the menu
• A scoreboard that displays at the end of every round
• The option to randomise the level each round

Also includes some minor fixes:

• Starting positions are now more evenly spread at the bottom of the level
• Only one Cavian should spawn at a time
• Boost pads have been removed from multiplayer (as they tend to kill everyone else!)

Also includes a change to the goal wording in Waldorf's Journey ("First to X" rather than "Best of X").

Compatible with version 1.7.6.0 of UFO50.
