modified:   luad/state.d - fixed assert for DMD 2.064.2 in

Here's a small fix for DMD 2.064.2, and a package.json file compatible with the current file structure for DUB building.

Not included in this pull request, but from my own experience: Linux 64 bit on DMD 2.064.2 gives an error at line 55 of state.d, _d_throwc in particular gives a segfault rather than throwing in the unit test. The only solution I've found was to replace the throw with a return and use another panic handler for throws.
