Initial ckan for KerbalAttachementSystem

Manual ckan for KerbalAttachementSystem. Needs to be a manual file since it is distributed on curse.
ps. This is my first pull request ever, I hope everything goes well ;)
Any chance we can change this (and the filename) to `KAS`? Given that the directory being installed is `KAS`, and the mod is in `KAS.dll`, that should make things consistent. (We may have to change some other metadata files, but that's cool.)

This also means we can *remove the install stanza entirely*, because the identifier matches the embedded directory we want, which is a pretty good sign we've chosen our identifier correctly. :)
