Narcissu 1+2 updated to new engine.

Narcissu 1 and 2 have been updated and ported to the same engine as the rest of the anthology. . This should help provide a more consistent experience with the rest of the anthology. Other changes in this update: * Translation for 1st and 2nd edited and updated to be consistent with the rest of the Anthology. * Presentation also standardized to voiced mode to be consistent with the rest of the Anthology * Launcher includes a button for the soundtrack, which opens the soundtrack folder for easy access * Japanese/English versions of 1st+2nd are accessed via steam's language properties, consistent w/ the rest of the anthology One tradeoff we had to make in this process was to standardize on a single translator for the whole series (Agilis). Users that prefer the other translations can always play them in the free Narcissu 1st and 2nd release, which remains 100% unchanged. http://store.steampowered.com/app/264380/Narcissu_1st__2nd/
