Building deb package via makefile. Update

- Junk, which was created in makefile.linux on previous attempt, is cleaned up.
- New file, wcm/wcm_version.mak defines version number. This is expected to be the only place that holds the number under 'wcm' directory. The number is propagated to the top of F1-help window, and is used in filenames for deb packages. Builds, which are prepared outside of makefile (i.e. without proper define in CFLAGS) show 'non canonical' for the version in the F1-help.
- Tested build process ( build-deb-package make target) on Ubuntu 14.04 in i386, and amd64.

*** How to see that it is working.

In wcm directory:

make build-deb-package 
builds deb package for current architecture. 

make debclean
cleans all deb artifacts from the build process

Build process shows meaningful messages when it  needs extra packages to be installed to complete the build.
