Umd 3 htcondor

Here is first version of the templates for configuring Cream-ce with htcondor batch system. A number of features is still missing (e.g. possibility to run cream and htcondor master on 2 different machines).

Usual convention in the template library is to ident 2 spaces (rather than 4) per identation level and to align (vertically) function arguments, i.e.:

```
'/software/components/filecopy/services' = {
  #Put the cluster Key file
  SELF[escape(CONDOR_CONFIG['pwd_file']+'.encoded')] = nlist('config', CONDOR_CONFIG['pwd_hash'],
                                                                                                         'restart', format('base64 -d %s.encoded > %s',
                                                                                                                                  CONDOR_CONFIG['pwd_file'],
                                                                                                                                  CONDOR_CONFIG['pwd_file']),
                                                                                                         'perms', '0400',
                                                                                                        );
