The Bat! 4.2.42

[-] A buffer overrun when selecting text in some messages has been fixed.
[-] Now The Bat! displays in the "About" box the information on the registration key: until which version the registration key is valid.

[-] "Connection Centre" display bug, which might occur when scrolling the window.
[-] Sometimes the transparent "Details" section of the "Connection Centre" was displayed with wrong background.
