Lctools

- Add possibility of GoGrid node RAM printing using
%(ram)s format string

- Decode format string using 'string-escape'

- Allow setting current profile not only via '-p'
option but via LC_PROFILE environment variable also

- Make lc-node-do process all nodes that were specified in
'-i' instead of failing on the first non-existing one

- Implemented lb-* scripts to work with load balancers
- Fix imports for libcloud version 0.5.x
- Switch to new version numbering: new scheme is:

$libcloud_version.$lctools_version

Where libcloud_version is the version of libcloud
which was used for lctools's current version development
and testing. And lctools_version is a numeric lctools version.

- Added tool to list GoGrid IP addresses: lc-gg-ip-list:

lc-gg-ip-list lists all ips for account
lc-gg-ip-list -a false -u true lists public \
unassigned ips

- lc-node-add nows accepts 'ip' arg for GoGrid with the IP
to use for a node, like:

lc-node-add ..... ip=10.0.0.1 where 10.0.0.1 is \
an ip you want to assign to node

- Added tool to edit GoGrid images: lc-gg-image-edit.
Brief info on usage:

lc-gg-image-edit -i <image_id> -t true \
-n new_name -d new_descr

Here, "-t true" tells that given image should be
public (i.e. visible to all GoGrid users),
"-n new_name" and "-d new_descr" update image name
and description respectively.

- Added tools for controlling Rackspace shared
IP groups: lc-rs-ip-group-list and
lc-rs-ip-group-do

- Added config file option for SSL certs verification.
Please add the following to the profile for which
you want to enabe verification:

verify_ssl_certs = true

By default it's disabled.

- Added GoGrid specific script: lc-gg-node-edit
which allows to change node's amount of RAM
and description. Sample:

lc-gg-node-edit -i <node_id> -s <new_size>

- Added ranges support for lc-node-do's -i arg, i.e.
if previosuly to remove nodes with ids like
1001, 1002, 1003 you had to issue command like:

for node in 1001 1002 1003; do \
lc-node-do -i ${node} destroy; done

now you just do: lc-node-do -i 1001,1002,1003 destroy
or even: lc-node-do -i 1001-1003 destroy

- Refuse to work if config file permissons are loose
