Title: Fix examples in geom_text

In the first changed example, using `aes()` made it overplot the same text many times. I also changed the data frame to `NULL`.

In the second example, I changed the documentation to reflect the code. The code uses `family`, not `fontfamily`. However, this might actually be a bug -- in NEWS, it says that it uses `fontfamily`. @kohske, is it a bug in the documentation, or in the code?
