Bump version to 0.13rc5
Don't try to verify SSL connection with '-k'

Kamaki would try to verify the SSL connection even when '-k' flag was
given and then would fall back. This doesn't work because we cannot use
the same socket twice.
Fix bug of incorrectly suppressed errors in CLI

Fixes grnet/kamaki#56

The bug is limited in "kamaki create network"
Set default logger to astakosclient.AstakosClient

Fixes grnet/kamaki#58

This bug fix refers to the LoggedAstakosClient wrapper.
The class AstakosClient is not forced to use a default logger.
Show the correct name when switching kamaki users

Fixes grnet/kamaki#66
Restore compatibility with Python 2.6 in HTTPS cls

Fixes grnet/kamaki#73

The problem is caused by the argument "source_address' when
instantiating "httplib.HTTPSConnection" in "kamaki.clients.utils.https"
This argument was added in Python 2.7, therefore a TypeError would
ensue with Python 2.6
This is fixed by catching the TypeError and retrying without the
"source_address" argument.
Fix Python 2.6 compatibility with string "encode"

String method "encode" accepts named arguments only since Python 2.7
Rename "raise_ssl_errors" to "ignore_ssl"

Refs grnet/kamaki#74

The modified flag is located in HTTPSClientAuthConnection of
"kamaki.clients.utils.https".
The default flag value is reversed.

Also, rename the method "patch_to_raise_ssl_errors" to "patsh_ignore_ssl".
The boolean values passed to this method is also reversed.

Update documentation accordingly.
Fix minor test, warning & pep8 issues (Python 2.6)

A bug is fixed in the test of "add_subcmd" of "kamaki.cli.cmdtree".
A warning on using the deprecated "message" name in ClientError has been
dealt with.
Pep8 issues concerning the modified files are fixed.
