HexEditor: Change cursor type from caret to black box

Browse source 
This patch changes cursor type from caret to black box for both Hex and
Text modes, because right now the way how blinking caret looks like is
more closer to "insert" mode in similar editors, whereas the real
behavior of this cursor is more of a "replace" mode seen in similar
editors like GHex.
