* remove ParentFont flag from forms again (introduced in 9cdcd631454f6f9e999893ea89fcf502d994474c for #213). This just inherits from default Windows settings.
* instead, scale font size in InheritFont(), and move that to the new TExtForm class
* mark app with PerMonitorV2 support
* drop workaround for application crash on WinXP, when loading newer libmariadb (see #79)
* raise TDbLib's own exception instead of baking an own one with less details. Probably helps in debugging: https://www.heidisql.com/forum.php?t=34044
* rename EDatabaseError to EDbError, to overcome naming conflict in DB unit
* load libpq.dll always with path, which should anyway work better than without it. See http://www.heidisql.com/forum.php?t=22514
* Introduce TAppSettings, created in dpr file
* Implement read and write methods, and replace callers of GetRegValue and MainReg.WriteInt/... with these
* Optimize read and write methods for avoiding redundant accesses to registry
* Auto-remove stored default settings from registry to avoid registry spam
* Replace synced MainForm.pref* variables with TAppSettings.Read* calls
* Move SetLocales call to dpr file
* Move MainForm.FDirname* variables to appropriate methods in helpers.pas
* Implement TQueryHistory.Create(SessionPath), reading its items within constructor
- Move QuoteIdent() and DeQuoteIdent() out of TMySQLConnection, make them classless
- Remove TMainForm.mask(), instead always use QuoteIdent()
- Introduce a third parameter to QuoteIdent(): "AlwaysQuote" - setting this to false will quote only if required
- Set AlwaysQuote to false for all stuff which drops some code into the query editor, see http://www.heidisql.com/forum.php?t=6986
- Remove ensureValidIdentifier() and its partly uncatched exceptions. Instead, disable "OK" buttons for empty table/view/proc name.
- QuoteIdent and DeQuoteIdent now take the glue char instead of a "HasMultiSegments" boolean param, so they're more exact when "user@host" or "db.name" come in.
* Remove workaround for Unicode text to and from clipboard
* Fix writing/reading wrong encoded text into/from registry - no need to use Utf8Encode() any longer
* Implement TMySQLQuery.ColAsAnsi() for cases in which we read binary data.
* Removes TNT Unicode controls, which are no longer required. All VCL controls now have native Unicode support.
* Remove Delphi 11 packages, otherwise we would either need to keep TNT or break Unicode
* PngComponents update from Uwe Raabe on http://cc.embarcadero.com/Item/26127
* Adjust auto build process
* Since Delphi 2009, Strings are now UnicodeStrings, not AnsiStrings any longer. Fix a bunch of compiler errors which came along with this change.
TODO: Project should compile but give tons of compiler warnings.
* Instead, use separate SHOW commands for tables, functions, procedures and triggers
* Catch this chance to move these methods from main unit to mysql_connection, so they're accessible in a more generic way
* Additionally, introduce new classes TDBObject and TDBObjectList which provide a more generic way than TMySQLQuery to access these database objects.
Fixes issue #1529
* Keep only one TRegistry object in memory instead of creating a new one in each routine.
* Move out relevant functions and TRegistry object from main to helpers to make them usable globally.
