[REL] v2.0.0-beta-11

# v2.0.0-beta-11

Yet another release with some small fixes.

[FIX] fix some issues with t-out with falsy values, and with default values
[REF] app: slightly simplify the create component path
[IMP] compiler: add support for binary operators
[IMP] add support for t-call-context directive
[FIX] properly get component reference instead of context
[FIX] blockdom: fix crash when class object key has leading spaces

 - a constructor: this should describe the type, for example: `id: Number` describe
   the props `id` as a number
+- an object describing a value as type. This is done by using the `value` key. For example, `{value: false}` specifies that the corresponding value should be equal to false.
 - a list of constructors. In that case, this means that we allow more than one
