Asymptote

Arbitrary depth array constructors were re-instated. Profiling code was added. Spaces within file names and eps file attachments are now supported in inlinetex mode, and interference from any pre-existing aux file is avoided. A new auto-generated version (1.21) of asymptote.sty contributed by Will Robertson features a latexmk-compatible asyinclude command. Path-overwriting bugs in the NSIS MSWindows installer were circumvented.
