Rename DominatorsAnalysis to reflect exception handling strategy

[gamesh411]

Dominators analysis available thru ClassContext performs an analysis that
disregards exception edges. References to DominatorsAnalysis were renamed to
reflect this.

Make ClassContext API for DominatorsAnalysis more descriptive

Dominators and PostDominators analyses are made available via
ClassContext API in exception-ignoring and implicit exception-ignoring
variants.

• Added an entry into CHANGELOG.md if you have changed SpotBugs code

Hey!
Regarding this patch:
I have noticed that spotbugs/src/sampleXml/analysisResultsWithFilterAndUserAnnotations.xml references these classes. I have introduced new classes and I don't know how to generate that XML file to update references inside the sample XML. I would gladly update those as well if you could point me in the right direction as to how the contents of the XML is generated.
Thanks :)

Thanks for the quick response! Fixed the license.
BTW, do you prefer if I just add my fixes as separate commit (like I have done now) and later squish the commits of the PR, or should I just rebase and force push as necessary?

Please don't force-push, it makes a mess.

Please add an entry in the CHANGELOG.md to tell renamed classes, it could be necessary for plugin developers.

Good point, I have summarized the naming changes in CHANGELOG.md.

Misspelled "Dominators" (and yes, the original was correctly spelled)

[gamesh411]

Thanks, spelling is hard (for me at least) :)
Ironically, while trying to fix one spelling error, I introduced another one.
(not to mention that the lesson learned here contradicts my current efforts on using less copy-paste in general xD)
