Big amount of changes.

*  upload app was not modified (except one little fix, of course)

*  new app "management"; it will be used for administration purposes (i.e. editing blog content, server file operations etc)

*  "blog" app will be used for displaying blog content and providing links to "management" app for editing its content

*  template structure:
    +  {appname}/pages/{template}.html will be used for rendering app-specific pages (they should have {% extends %} tag)
    +  {appname}/tpl/{template}.tpl will be used in {% include %} tags
    +  /slasyz_ru/templates/base/{template}.html will be used as page base in global design (full page with header and footer or its part needed only for ajax)

    In next commits some templates from /management/templates/management/ will be moved to /slasyz_ru/templates/.

    In management/pages/ there will be directories or name prefixes for each utility

*  static files structure:
    + These two files are app-specific:
        - /{appname}/static/{appname}.css
        - /{appname}/static/{appname}.js
    + These files are used in global design:
        - /slasyz_ru/static/base.css
        - /slasyz_ru/static/base.js
    + These directories contain libraries used in global design:
        - /slasyz_ru/static/foundation/
        - /slasyz_ru/static/jquery-ui/
Global templates was moved to /slasyz_ru/templates/global/
