Three libraries replaced with git submodules:

1. CryptoLib4Pascal
2. HashLib4Pascal
3. SimpleBaseLib4Pascal

This will make updating these projects in the future easier and
thus PascalCoin can benefit from any improvements or bug fixes
made to these libraries by simply fetching+merging or pulling
in the changes.

Delphi folder with pre-compiled files added:

1. Less memory used by compiler.
2. Faster compile times.
3. Dynamically loading run-time libraries becomes possible
for PascalCoin.

ProjectGroup added to help re-compile submodules for different
delphi compiler versions.
