Fixed an issue in the Left 4 Dead list where some tracks wouldn't play.

The Portal list has finally been reworked to include the full Portal 2 soundtrack.
However due to the amount of tracks in the album, it is now separated from this initial addon.

Link to the addon, for those in desperate need for it.

Portal 1's soundtrack are still playable whether or not you've installed this addon, as long as you have the game mounted.

Opposing Force's soundtrack is now merged into PlaySound Improved, meaning that you will no longer require a separate addon to download.

On a side note, I might consider reworking the Portal soundtrack list soon.

Added the horde themes from Left 4 Dead and Left 4 Dead 2.

Removed an extra "-" in the Portal list.

Minor changes.

Changed the addon's title.

The Black Mesa soundtrack has departed from PlaySound Improved as a separate addon, so people wouldn't need to download all of them when subscribing to this addon.
