re-enabled caching of manifest, but correctly this time. Updated installation instructions accordingly
started with server profiling (built-in to Code Igniter)
make file input less ugly in normal view and print view
remove jr: namespace prefix from templates in instance (my new dev server includes the prefix, probably due to a php update, which breaks repeats)
Merge pull request #274 from modilabs/design_improvements

manifest caching is back, fix for repeats, upload input styling
