FreeRails: Import of original sources

I imported the releases on the FreeRails I, II, III projects on Sourceforge and saved the available source package in a branch of the Github repository. I also re-released some of the historic available versions.

• Last release (0.2.7) of FreeRails (2000-2005) Link
• Last release (0.4.0) of FreeRails2 (2007-2008) Link
• Last release (0.0.4) of FreeRails3 (2016) Link

The Railz I, II projects on Berlios (exported to Sourceforge) are also saved in a branch of the Github repository. Some re-released versions are

•  Last release (0.3.3) of Railz (2004-2005) Link
•  Last release (0.4.0) of Railz2 (2012-2014) Link

 These branches and releases cover the existing development as far as I know it.
