initial import of v0.42
Adds fenixsql application - Firebird database management application

* imported from original fenixsql code
* made some project options changes
* converted one form to use TPageControl instead of buggy TNotebook
* opened all forms so old deprecated properties could be removed. The original
  fenixsql was developed with a very old Lazarus.
Merge fenixsql project as our subdirectory
fenixsql: Normalization of line endings

* Moved source code into its own sub directory 'src'
Renamed the "SupportApps" directory.
Updated the readme file
Made the licensing terms more clear.

We specify the "static linking exception"
Updated the FILES file, and fixed some spelling mistakes
Removed old batch & script files.

* clear.bat is not needed, we can simply us 'git clean' instead
* makehelp.* will be replaced with fpdoc based help. That way we can
  support HTML, CHM, PDF, INF etc help formats.
