The program was completely rewritten with libacpi, and new options were added for every feature (along with an option to enable every feature). Interactive input for delay in ncurses mode was removed in favor of just restarting yacpi. The program instantly reacts on user input in the ncurses interface and select loop. The -m optin was removed so that you always get all batteries without a performance deadlock, and samples are no longer used.
Code cleanups. The default behaviour of sample usage has been changed. Without specifying samples, the remaining battery time is now remaining capacity / present battery rate like in most of the ACPI tools. There are small man page adjustments.
