Rename network type "MySQL ..." again to "MariaDB or MySQL ...", and name it "MySQL" only if we're sure it's not anything else. This is a bit hacky, as I have to leave IsMySQL a bit inexact, so it still matches servers with version_comment="Source distribution" (see issue #1099 )

Issue #477 : Attempt to fix crash in main form due to refreshed database objects after creating a table via CSV detector:
...
* TDBConnection.GetDbObjects now leaves old object references intact if a table still exists after a refresh
* Restructure caching of columns, keys and foreign keys in generic TDictionary typed lists. This should make GetTableColumns and friends safe against endless recursion.
* Probably fixes issue #319

Issue #1028 : Fix one-time recursion in TMySQLConnection.FetchDbObjects, caused by accessing InformationSchemaObjects, which in turn calls GetDBObjects and then again FetchDbObjects. More dramatically, this caused GetTableColumns to do an endless loop with two cache entries for "information_schema". This also fixes many of the v11.0 crashes in TAppSettings.PrepareRegistry, which were just a symptom of that endless loop. Thanks to als2020 on Github for pointing me in this direction.
