Fixed one typo in response_helpers which caused is_admin context variable not to work correctly. Created new checkLinkNameForId function that checks if link_name is correct when creating new user and modifying existing one. This is now used for validation instead of doesLinkNameBelongToId in UserForm clean_link_name function. The previous validation function didn't allow to create new users and modify linkname of existing ones. Additionally I created new doesLinkNameExist helper function.

VERSION = (0, 97, 'pre')

def get_version():
    "Returns the version as a human-format string."
    v = '.'.join([str(i) for i in VERSION[:-1]])
    if VERSION[-1]:
        from django.utils.version import get_svn_revision
        v = '%s-%s-%s' % (v, VERSION[-1], get_svn_revision())
    return v
