Stick to version consistency, build_master.json must specify minimum required version of build master

• build_master.json must have a key "version" which would hold value as "1.0.0", executing build master would check its version against this version specified in build_master.json
• The build_master.json may also have "major_version", "minor_version", and "patch_version" keys separately.
• Bump bug/fix version of build master each time a bug is fixed
• Bump minor version of build master each time a very a feature is added or improvement is made but it is still backward compatible
• Bump major version of build master if at least non-backward compatible feature added or improvement is made
