Implement diffing relocations within data sections (#154)

Browse Source 
* Data view: Show data bytes with differing relocations as a diff

* Data view: Show differing relocations on hover

* Symbol list view: Adjust symbol/section match %s when relocations differ

* Improve data reloc diffing logic

* Don't make reloc diffs cause bytes to show as red or green

* Properly detect byte size of each relocation

* Data view: Add context menu for copying relocation target symbols

* Also show already-matching relocations on hover/right click

* Change font color for nonmatching relocs on hover
