Update uglify-js dependency version
Compiler now inserts `__.bd=1` into templates if they contain any block declarations, even if the block is not declared at runtime
Cleanup runtime: remove unsafe block action stuff, etc.
Includes now check `info.bd` to see if the included template contains any block declarations; if not, the included HTML can be safely captured and wrapped in a branch label (closes #116)
"foreach" items are now separately reactive and wrapped in `LiveUpdate.isolate` calls
Push to 3.0.0beta4
