Make an error message nicer
Remove 'plaintextPassword'.

'password' can always be either a string or an object (indicating that
it's been hashed already with something). When the server receives a
string, it hashes it with SHA256 before bcrypt.
Extract number of bcrypt rounds to top of file
Merge branch 'srp-to-bcrypt' into devel
Don't decrement the line number in LESS error reporting.

LESS fixed their math problem in 1.6.0
Allow external CSS style attributes to interop with Blaze style attributes. This fixes cases where jQuery calls .hide() or .show() on an element which also has a Blaze defined dynamic attribute.
Update StyleAttributeHandler to prevent conflicts in css styles. This fix will ensure that Blaze and external javascript cannot both set the same property on an element. If both Blaze and external javascript modify the same property, then the most recent modification will win.
Test the interpretation of event map selectors

If you listen on “div p”, for example, both the div and the p have to be in the template.
