 general tools for used in other apps * moved 'templatetags' from
 'apps/indicator' to 'apps/utils' * '.gitignore' to ignore 'fixtures_bak' *
 moved js plugins from 'apps/indicator/static/plugins' to  
 'staticfiles/plugins'

apps/recommend:
* updated 'recommend.models';
    o commented 'recommend.models.ResearchCombination' (not used)
* implemented views 'add_edit_blog_info' and 'ajax_add_edit_configs';
* added pages 'templates/recommend/add_edit_blog_info.html',
    'add_edit_blog_info_error.html';
    o related css and javascripts files
* added 'tools.py';

* added 'utils/tools.py' for placing generic functions;
* deleted 'initial_data.json' (mv 'fixtures' to 'fixtures_bak');
