notice: remove meaningless digital in version string.

[zhangn1985]

current version is 1.1.4.1
as guided by http://semver.org/ , I rethink the version of the project.
first digital:
first digital, major version, 1 for CLI interface, 2 for GUI
second, minor version, impotent changes are made
third, patch version, small fix, no larger than 9.

so change next version string to 1.4.2 , remove first meaningless digital.
