This commit is a preparation for the configuration file parser.
The `int attr_*` variables have been moved into a separate struct.
Members of that struct are alphabetically ordered, so an attribute can
later be accessed by its name.
Added `int get_color_pair(short fg, short bg)` for returning or
creating a color pair number.
Added call to `use_default_colors()` for enabling access to the
terminal's default color (-1).

Mouse support has been added for mixer_widget.c, card_select.c and
proc_files.c.
In the mixer widget the mouse is handled as follows:
- After an element has been printed in mixer_display.c, a call to
clickable_set() will store the coordinates of the drawn area plus the
command enum that should be executed on click. An optional argument
holds an index which points to the selected mixer control.
- on_mouse_click() searches for a matching rectangle, focuses the mixer
control and returns the command enum.
In the menu widgets, the menu_driver() function handles mouse input.

This commit is a preparation for making keybindings configurable.
The hardcoded keys in the switch statements of mixer_widget.c,
textbox.c, proc_files.c and card_select.c have been replaced by
command enums. The command that shall be executed is looked up in
the arrays `mixer_bindings` and `textbox_bindings`.
The channel_mask enum has been made public, since LEFT and RIGHT are
used as command arguments in bindings.c.
