Fix #148 calil.error Should Accept XMLHttpRequest object as HTTP error
Don't flash any errors while the page is unloading (such as terminating HTTP requests)
Don't catch/log RDFa parse errors, just throw them up the call stack
Use If-Unmodified-Since request header instead of If-Match to avoid extra HTTP HEAD request (to read initial ETag)
Add calli.submitTurtle and calli.submitUpdate functions
Add ajax wrapper for simple HTTP requests
Add calli.submitFile
Make ajax errors opt-in (not opt-out)
