0.2.1

Added

• Most types now implement Send. (#53)
• All tags now support the ARIA role attribute. (#47)
• The text!() macro now accepts expressions as value arguments. (#48)
• You can now create "unsafe" text nodes with the unsafe_text!() macro, which won't be quoted at all when stringifying, even if they contain HTML tags. This is a meaningless distinction when creating DOM nodes, however, and unsafe text nodes will behave like normal text nodes in this case. (#39)

Changed

• Text in attributes are quoted less aggressively when stringified. (#26, #49)
• Attribute type conversion is now using the recently stabilised TryFrom instead of From, to avoid relying on panicking From implementations to detect conversion errors, though the conversions inside the macro will still panic if they fail. The appropriate TryFrom implementations have been added to Class, Id, SpacedList and SpacedSet, and the corresponding From implementations have been removed.
