* Remove helpers.DetectEncoding(). Use a separate TStreamReader in the only caller to detect the encoding of a selected file
* Remove helpers.ScanNulChar()
* Remove helpers.RemoveNulChars()
* 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
* 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.
* Move const.inc and compilers.inc back to main source directory
* Move remaining few lines of code from heidicomp.pas to helpers.pas
* Remove components/compilerdetection and components/heidisql
* Remove remainders of EDBImage component, unused since Aug 08.
a) Detect current linefeed style
b) Convert all linefeeds to CRLF
c) Let the user chose a different one or leave it as it is
d) Convert linefeeds back to selected before saving
* 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.
* Add a few notes about where AVs seem to randomly occur when GridPost{Insert,Update,Delete} and EnsureDataLoaded invokes the query logic from outside the main thread.
Fixes issue #659 as far as the grids go, but not for export functions.
