deleting/moving files causes problems

[dominicbarnes]

I've noticed that renaming or deleting a file causes subsequent builds to fail. I've not investigated the root problem yet, but I suspect the deleted files are still in the tree and being run through plugins. (so I'll need to come up with an elegant way to detect this case)

I actually discovered the root problem. I'm working on an electron app, for which I'm generally just transpiling JS files in-place, rather than bundling them. Thus, when using mako-watch, the rebuilds are using the same initial list of entry files, and not recomputing them when files are moved around. (forcing me to restart the watcher each time I rename/add/delete a file, since they're all entries)

I'll take a look at the watcher to see if this is an easy fix to make.
