HexEditor: Add Value Inspector
This adds a value inspector window to the Hex Editor. This window shows the data at the current cursor position (or selection start if a range is selected) interpreted as a variety of data types. Currently supported values include 8, 16, 32, and 64 bit signed and unsigned values as well as float and double. The inspector can operate in both little endian and big endian modes. This is switched between by options in the View menu.
