Attachment bug in olog script

[dejande]

Hi.

There is an error when calling an olog script with "-a" parameter.

Traceback (most recent call last):
  File "./olog", line 151, in <module>
    olog()
  File "./olog", line 125, in olog
    attachments = [Attachment(open(a)) for a in args.attach.split(',')]
AttributeError: 'list' object has no attribute 'split'

By removing ".split(',')" in

https://github.com/Olog/pyOlog/blob/master/scripts/olog#L125

uploading attachments works.

Also if you want to upload multiple attachments with the same name you get the following error:

Traceback (most recent call last):
  File "./olog", line 151, in <module>
    olog()
  File "./olog", line 148, in olog
    client.log(log_entry)
  File "/usr/local/lib/python2.7/dist-packages/pyOlog/OlogClient.py", line 82, in log
    resp.raise_for_status()
  File "/usr/lib/python2.7/dist-packages/requests/models.py", line 825, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 409 Client Error: Conflict

Python 2.7.9
requests 2.4.3
