Added btnlook example.
Fixed a formatting issue.

The formatter was inserting commas because of a format command that was
left in from testing.
Added variation of btnlook example.

Added a variation to the btnlook which uses the system color and updates
itself on WM_SYSCOLORCHANGE event.
Added owndraw example.

The owndraw example shows basics of using the BS_OWNERDRAW button type.
Added color1 example (untested).
Got the color1 example working.
Fixed small issue with tabbing between scrollbars.
Added first poppad example.
Started on environ example.

The environ example shows using the listbox control to display
environment variable data.
Figured out how to parse the var name.
The environ example mostly works.

I'm getting memory errors when an item is selected in the text box which
is probably related to calculating the memory needed to allocate one of
the string buffers.
Fixed crash.

Turns out that LB_GETTEXT and GetEnvironmentVariable were not returning
the number of bytes in a string but rather the number of (abstract)
characters (as opposed to the char or byte type).
Started the head example.
Finished writing the head example.

The code is complete for the head example but haven't tested/debugged it
yet.
Got head to compile without errors.
The head example seems to be working well now.
