Deprecating old versions

[mehan alavimajd]

It seems a lot of old versions have bugs.
For example about v1.3.4, It's impossible to run hascal because of it Makefile.
giving error:

Makefile:8: *** missing separator.  Stop.

We must put this bugs in docs so users won't install this bad versions.

v1.3.5: Impossible to run makefile.
Error:

Makefile:8: *** missing separator.  Stop.

v1.3.6 and v1.3.7: Unable to run.
error:
