function touch_icons_update_6100 in Touch Icons 6

Implementation of hook_update_N().

After 6.x-1.0-beta4, the names of the theme settings variables for the icon file paths were changed...

OLD: touch_icon_path_plain NEW: touch_icon_plain_path

OLD: touch_icon_path_precomp NEW: touch_icon_precomp_path

This update tests for the old style variable name, and migrates it to the new style variable name.
