Parse PE resources

[xusheng6]

It would be a nice addition to parse the PE resources, and even better, display all the resources in a tree view similar to that in Resource Hacker. This can be divided into two tasks:

1. Parse and define the relevant structures in the resource directory
2. Add a new view to display the resources

1). is super easy to do, as it simply deals with some structures. But it could already be useful in certain cases. 2). is a more robust improvement, but it is not super useful for analysis. So it has lower priority.

Parsing of PE resources is added in 4.1.5288-dev. Resource names aren't resolved though.
