Title: Extended the cat-log command to task logs

This user guide tutorial related change allows ```cylc log``` to print task as well as suite logs:
```
cylc log my.suite # print suite event log
cylc log -o my.suite # print suite stdout log
cylc log -e my.suite # print suite stderr log
cylc log my.suite foo.1 # print foo.1 task job script
cylc log -o my.suite foo.1 # print foo.1 task stdout log
cylc log -e my.suite foo.1 # print foo.1 task stderr log
```
It also removes the task filtering option from the command - just use grep.
