teensy patch, doesn't break 0.6, lets devs work with 0.8 if they want to and lets us start exploring it. (really all this does is eliminate deprecation warnings)
@jedp notes that I overlooked the fact that 0.6 fs has no .existsSync - doh! I swore I tested that! he's taking the PR and will patch
Jeeeeesus! Sorry about the rebase mess. It seemed I needed some of those earlier updates. But oi, sorry.
Here's my bit - just a wrapper for existsSync! Commit 09f65ff
support node 0.8.x
existsSync wrapper to use path (node 0.6.x) or fs (0.8.x)
r+ on jedp's update to this patch. tested on 0.6 and 0.8 - no deprecation output on console from unit tests.
