    config.py: Fixes package version checking regression
    
    Previously webapp-config would not do any sanity checks when
    setting the package version. After adding a sanity check in 1.54
    I made the mistake of not being flexible enough and this caused
    a regression that prevented web apps with versions such as
    "20140929d"[1] to be installed. This commit fixes that while still
    allowing for some sanity checking.
