Allow passing list of props to element props

[fernandovalera]

When rendering an element, allow passing a list of props which are merged from into a single table from right to left.

e.g.: { { prop1: 1 }, { prop1: 2, prop2: “hello” } } would resolve to { prop1: 2, prop2: “hello” }

Use case: In addition to custom props, pass in element or component specific theme/context props in one expression instead of many lines.
