[Fractdev] diskisactive

It appears that the only place this is used is in startdisk() where it returns without doing anything if this is set. However, throughout the code there is this pattern: diskisactive = 1; savetodisk(savename); diskisactive = 0; Which seems to imply that the function savetodisk() is affected by this flag, but that isn't the case. In the branch, the only place startdisk() is called is from the driver code, so I am going to remove this variable and only call startdisk() when appropriate in the driver. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>
