Update Jade to version 0.27.2

1. Synced official Jade repo from TJ.
2. npm install, make clean (looks like TJ has not recompiled in his
branch as it still had v0.26.x in the root), make all.
3. Update jade.js(require-jade) from line 10 to line 3365 with newly
compiled jade source(TJ's repo).
4. Modify the require("jade") statement (line 3629) to work with
existing wrapper.
Make templates work after build even if excludePragmasOnSave.excludeJade is not defined.
