Change anchored_artists.AnchoredSizeBar: docstring, vertical size, color

- Add size_vertical variable, which sets the height of the size bar.

- Docstring: listing the possible arguments and adding an example.

Update of finance.py to (O,H,L,C) instead of (O,C,H,L)

In the financial world, a bar-chart is commonly called an OHLC-chart or "Open-High-Low-Close chart". Also see http://en.wikipedia.org/wiki/Open-high-low-close_chart or simply google around.

To my surprise this library uses a sequence of OCHL instead of OHLC. Although it changes the API, I found it important to comply with financial industry standards. This makes it easier to implement this library in existing financial software and thus more likely to be used in the future.
implemented the wrappers discussed in #1783.

Added deprecation warning to `plot_day_summary2` and returned call
signature to what it was.

Added alias `plot_day_summary_ochl` with same call signature as
`plot_day_summary2`.

renamed the modified function to `plot_day_summary_ohlc`.

The first two functions simply call the third with the arguments
re-ordered.
