While it is not tested, nor documented, the reference QWeb
implementation display the `false` value as "false". So, we have to
adapt the Owl implementation to match that behaviour.
At the same time, this commit uses 'let' instead of 'var' in various places,
to make the compiled code more consistant.
Before this commit, the handlers were bound to the current context,
which is often the component but not necessarily. In some cases, a sub
scope can be created (with t-foreach, or slots, or t-call), and the
context is actually an object with the actual component instance it its
prototype chain, but not the component.
- In some cases, we can simply inline a template key instead of assigning
it to a variable and then using that variable
- Add component name in generated code for components
