New style sheets not monitored by gulp dev

[mweint]

Create new .styl file and it will not update the page until you recall gulp dev

Could not reproduce. May already be fixed.

[mweint]

Only occurs in lib directories that don't currently have any .styl files in them yet

This appears to be an issue in gaze. I created an issue here: shama/gaze#70

This issue may also be related:
gulpjs/glob-watcher#4

When these are resolved, we can update and fix it.
