[IMP] compiler: generate templates in strict mode

Before this commit, generated template functions were not using strict
mode. This may be a bad idea, since strict mode could be more performant
in some cases.

 - 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
   type. For example, `id: [Number, String]` means that `id` can be either a string
   or a number.

+Note: by default, the rendering context for a sub template is simply the current

 ### Dynamic sub templates
 
 The `t-call` directive can also be used to dynamically call a sub template,
