UT 0.19.6, UE 0.3.5, UP 0.2.5

Browse Source 
- added support for firmware volumes with CRC32 stored in ZeroVector
(Apple UEFI feature)
- ZeroVector included to FV information
- added new volume types AppleCRC, AppleCRC Boot and AppleCRC Unknown
- added support for HP POSTCode sections
- size information split into header size and body size
- decimal sizes are added, shown in braces after hexadecimal sizes
- corrected small bug with Extract Body action being enabled for items
with empty body
