Filter does not work when table name has spaces

Problem Description:

  When the DataTable name (as defined in the 'name' field of the
  Meta class in tables.py) has blank space, filters defined on that
  table using FilterActions wont work.

Cause:
    -table name is used as the table id in the html
    -the table selector used in the quicksearch plugin has the
     following format:
	 table#<table id> tbody tr

     For example: if the table name specified in the Meta class of
     tables.py is 'foo bar', then the table selector will be:
         table#foo bar tbody tr.

Solution:
    Slugify the table name and use the slug name as the table id
    instead of original table name.

Fix cancel button size in modal dialogs

The cancel button in a modal dialog is being modified by different
css classes than the other buttons "submit/ok/etc.." This is due
to an explicit .close button class in _close.scss. Adjusting that
would have wider ranging ramifications than just the modal dialog
close/cancel buttons, so instead I modified the existing font
size to make it match the submit button, and explicitly set the
line-height to the default (.close has its own line height setting
that doesn't match whats in .btn).

set max_length on volume/snapshot description text area

Currently, there is no max, but will close the modal and give
the generic "Unable to update volume." This is a preventable
error if we restrict to 255 chars to match Cinder.
