QHexEdit is now based on QIODevice, can edit large files

Release 0.7.0, 2015-05-18

• QHexEdit is now based on QIODevice. The data shown is not buffered in memory. QHexEdit can show now very big files (> 2 gigabytes) without any problems
• QHexEdit has also a QByteArray based, backward compatible (as far as possible) interface for convenience
• Changes on the data will be stored in copied memory chunks, the base file will only read (QIODevice::ReadOnly)
• QHexEdit is now directly derived from QAbstractScrollArea
• The Widget calculates now all dimensions dynamically, hence small or big fonts will be shown properly on all screens
• You can use also proportional fonts, though it is not recommended
• Paint event needs very low cpu activity, when editor is in idle mode without user actions. Only the section of the data is rendered, which is shown to the user
• Several bugfixes.
