Display-related Enhancements in Epsilon 13

The new define_color_class( ) primitive lets EEL code directly define new color classes. It can also create anonymous color classes.

Modes where indentation doesn't affect highlighting rules can use the new COLOR_IGNORE_INDENT macro to get better performance.

EEL can now define regions whose spots will automatically be deleted when the region is. The modify_region( ) primitive now recognizes the new MRAUTODEL code to enable this.

When building the mode line, Epsilon now calls any function whose name starts with show_minor_mode_... to add the name of any minor mode currently in effect. This makes it easier for an extension to define a new minor mode.

The new buffer_color_scheme variable lets a buffer specify a particular color scheme instead of the default one; it's similar to the existing window_color_scheme.

The bprintf( ) family of functions now recognizes the flag character ' to request commas in decimal numbers. For example, the format string %'d formats the number 12345 as 12,345. And they now recognize the new %e sequence to interpolate the text for an Epsilon error code.

The button_dialog( ) primitive now sets the variables key, full_key, and key_is_button to indicate exactly how the user responded to the dialog, in addition to returning a code saying which option was selected.

The new disable_dialog_controls primitive variable lets EEL code disable buttons and check boxes on a dialog under Windows.

The new count_windows_with_buf( ) primitive tells how many windows display a certain buffer.
