Add option to display bytes in B, KB, MB, GB, or Smart formats (see bug 437626). The default is to always display in Bytes format to match the previous MAT behavior and not cause any confusion. The option can be changed in the Eclipse perference dialog or using -Dbytes_display=(bytes|kilobytes|megabytes|gigabytes|smart). In Smart mode, if the value is a gigabyte or more, display in gigabytes; similarly for megabytes and kilobytes; otherwise, display in bytes.

443247: Add preference to hide welcome screen on launch
Adds a new preference "Hide Welcome screen on launch" which defaults to false. Therefore, this does not change the previous behavior. This option is only for power users who want to explicitly enable this preference to close the welcome screen on launch.
