Fixes first sentence delimiters

Scaladoc places the first sentence in the method summary table and index. The first sentence is defined as the sequence of chars up to the first period (not as in JavaDoc where the sentence ends with the first period *followed by a blank*). As a consequence, the clause starting with `i.e.` is interpreted as sentende delimiter. This request replaces `i.e.` with `i&period;e&period;`. Alghough a valid HTML code, I do not know whether this change is compatible with other tools. And I assume that this is not the only source file affected.
Did not know of the fix for SI-8672. Followed the recommendation given by som-snytt.
Update javadoc tag to new scaladoc tags.
Fix scaladoc typo
Fixed mathematically wrong statement in the documentation of scala.math.PartialOrdering.

- Previous (misleading) documentation suggested that a partial ordering *is* an equivalence relation. This has now been clarified.
- Existing documentation on properties of partial orderings (reflexive, transitive, antisymmetric) had several formatting inconsistencies that have now been remove.
