[usability]Need to wrap long lines in the "Tags" column

[Anastasia Kuznetsova]

Steps to reproduce:
1. Create workflow:
version: '2.0'

wf:
  type: direct
  tags: [taaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaag]
  input:
   - variable_that_has_a_really_long_name
   - second_variable_that_has_a_really_long_name
  tasks:
    hello:
      action: std.echo output="<% $.variable_that_has_a_really_long_name %>"
      wait-before: 1
      publish:
        result: <% $.hello %>

Observed result:
mistral workflow-update wf.yaml
+------+-----------------------------------------------------------+-----------------------------------------------------------------------------------+---------------------+---------------------+
| Name | Tags | Input | Created at | Updated at |
+------+-----------------------------------------------------------+-----------------------------------------------------------------------------------+---------------------+---------------------+
| wf | taaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaag | variable_that_has_a_really_long_name, second_variable_that_has_a_really_long_name | 2015-04-28 09:57:04 | 2015-04-28 11:21:19 |

NOTE:
the same problem is valid for tables: action-list, workflow-list, workbook-list
