new implementation for 'skip' and  'pending'

Hi,

I've implemented a new solution for skip. skip must be inside methods now.

example: 

````java
class SkipItSpek: ConsoleSpek() {{
    given("a situation") {
        on("an event") {
            it("should A") {
                skip("not ready yet")
                assertTrue(true)
            }

            it("should B") { }
        }
    }
}}
```

and also 'pending' has been added to mark not implemented features

exampe:

```java
class PendingItSpek: ConsoleSpek() {{
    given("a situation") {
        on("an event") {
            it("should A") {
                pending("not implemented yet")
            }

            //default pending.
            it("should B")
        }
    }
}}
```
