Enable line wrapping

[jensenr30]

Line wrapping can be enabled/disabled with a setting in Tools->Options->Diff->Wrap Lines. This closes #706.

All credit to Scintilla.

This addresses the second half of #514. The second half of issue 514 was: bad user experience when scrolling down through the DiffView. But with line wrapping enabled, the horizontal scroll bars disappear. That prevents the mouse scroll wheel from being captured by the horizontal scroll bar.

Demo:

wrap-lines.webm

wrap-lines-scroll.webm
