Windows: Script full generation of Windows build from scratch for version 1.4.

Aim to be able to automate the generation of Windows Viking Installer executable from scratch.
[Preferably from a Linux System using Wine]

Script to setup full Windows build environment (including various work-a-rounds),
 using old but known to work MinGW5.1.6 + gcc3.4.5 compiler and various dependencies.
Miscellaneous scripts to make this work via Wine.

TODO: In the future look to using the current MinGW (Dev System) with gcc4.6+
This should hopefully simplify the auto build environment.
