Make a whole pile of routines private to "colors.c" static, and remove

their declarations from "colors.h".  Do the same with some variables -
and remove the ones that aren't used any more.

Make some name changes suggested in the comments in "colors.c".

Make "color_delete_cb()" take, as the user-supplied argument,
"cf->colors", just as "color_new_cb()" does, and make it use its
argument to find the color filter, just as "color_new_cb()" does, rather
than using "cf.colors".

When there are no colors in the list, make the "Edit" button
insensitive; make it sensitive if there are any colors in the list, so
that we don't crash if you press "Edit" when there are no colors in the
list.

Make "remember_selected_row()" take, as the user-supplied argument,
"cf->colors", rather than "cf" - it needs only the color filter, not the
entire "capture_file" structure.

When using "gtk_clist_select_row()" to forcibly select a row, pass -1 as
the column number, to indicate that we don't care which column is
selected.

Fix some typos in function names.
