VMM/Config: LazyConfig.getboolean(), convert the value in our getboolean. So RawConfigParser hasn't to do the whole get() stuff again.

Added 'doc/build' to the ignored files.

VMM{/Config}: reduced docstrings. Added doc to the repository.

VMM: removed unneeded/duplicated regular expression definitions

VMM/Config: moved Config.sections() to class LazyConfig. No longer import the ENCODING from VirtualMailManager, it's no longer required in the Config module.

VMM/Config: renamed LazyConfig's get_boolean() to getboolean(). VMM/cli/Config: import required ConfigParser.RawConfigParser.

VMM/cli: added __init__.py to the repository.

VMM/{,cli/}Config: fixed imports. Small code cleanups and cosmetic.

VMM/Alias: small code cleanups and cosmetic.

VMM/Relocated: small code cleanups and cosmetic.

VMM/Config: LazyConfigOption.__init__() cast 'default' to 'cls'. If the default value is not None, make sure it has the proper type.

VMM/Config: attributes of class LazyConfigOption are read-only now. Some small code cleanups.

VMM: renamed function chk_domainname() -> check_domainname(). Moved EmailAddress.check_localpart() -> VirtualMailManager.check_localpart(). Some small code cleanups in class EmailAddress.

VMM/Domain: added function get_gid() to the Domain module. We don't need to load all the domain related information from the database, when we need only the GID of a domain. For example in the Alias or Relocated classes.

VMM/{Relocated,Handler}: reworked Relocated class, adjusted Handler.

VMM/{Alias,Handler}: reworked Alias class, adjusted Handler class. Handler: - attribute _dbh is no longer private, the VMM/cli/Handler uses it also. - adjusted to changes in Alias and EmailAddress classes.
