Feature - "Direct match" scraper module support for aliasMap.csv

[retrobit]

• Add support for aliasMap.csv to Screenscraper, ArcadeDB ("direct match", e.g. filename/hash) scraping modules, except for "local/utility" scrapers, like import or EmulationStation Game List scrapers
  • When a matching entry exists, will search instead by name defined as alias
• Extract constant lists of directMatchScrapers, searchMatchScrapers, and variableScrapers to scraperworker.h, representing all supported scraper modules
• Update aliasMap.csv comments to be more clear and follow new behavior
• Add multiple debugging statements
• Create new variables in addition to baseName to accurately represent strings they represent, for clarity, instead of recycling the same name
• Some scrapers were using QFileInfo.completeBaseName() and QFileInfo.baseName() ambiguously. I checked DB APIs behavior/expectations here and made sure to correct/make these consistent with what's expected

I apologize about the commit message getting muddled due to rebasing; I will edit it when possible and make sure to modify them correctly during rebases in the future 😀

Fixed commit message, rebased onto master resolving one debug newline statement in mobygames.cpp

Let me know if you have any questions when reviewing this PR. I noticed it's easier to read the changes with the "Hide whitespace" option, especially for a file like openretro.cpp:

Absolutely! Apologies for the wait, life happened. I will work on it as soon as I can!

OK the changes should have been reverted/made. Thank you so much for creating the test files... That's huge. I have no experience writing tests using the Qt framework, so I'm looking at them now and learning a lot.

Thanks for this and your endurance and patience.
