Improved delta values to support non-numerical values

Browse Source 
Delta values now work for non-numerical values. Any column,
when its value differs from its ref, becomes orange.

A column that was already a "delta column" keeps its previous
behavior (dupe cells for these columns are always displayed in
orange).

Sorting behavior, when Dupes Only and Delta Values are enabled
at the same time, has also been extended to non-numerical
values, making it easy to mass-mark dupe rows with orange
values.

Documentation was updated, unit tests were added.

Fixes #213

Delta Values

If you turn this switch on, some columns will display the value relative to the duplicate's reference instead of the absolute values. These delta values will also be displayed in a different color so you can spot them easily. For example, if a duplicate is 1.2 MB and its reference is 1.4 MB, the Size column will display -0.2 MB.
If you turn this switch on, numerical columns will display the value relative to the duplicate's
reference instead of the absolute values. These delta values will also be displayed in a different

is 1.4 MB, the Size column will display -0.2 MB.
Moreover, non-numerical values will also be in orange if their value is different from their
reference, and stay black if their value is the same. Combined with column sorting in Dupes Only
mode, this allows for very powerful post-scan filtering.
Dupes Only and Delta Values
---------------------------
The Dupes Only mode unveil its true power when you use it with the Delta Values switch turned on. When you turn it on, relative values will be displayed instead of absolute ones. So if, for example, you want to remove from your results all duplicates that are more than 300 KB away from their reference, you could sort the dupes only results by Size, select all duplicates under -300 in the Size column, delete them, and then do the same for duplicates over 300 at the bottom of the list.

Same thing for non-numerical values: When Dupes Only and Delta Values are enabled at the same time,
column sorting groups rows depending on whether they're orange or not. Example: You ran a contents
scan, but you would only like to delete duplicates that have the same filename? Sort by filename
and all dupes with their filename attribute being the same as the reference will be grouped
together, their value being in black.
You could also use it to change the reference priority of your duplicate list. When you make a fresh
scan, if there are no reference folders, the reference file of every group is the biggest file. If

the other will be ignored. And since you want the last modified file to be reference, having the
sort order descending assures you that the first item of the list will be the last modified.
