Add check for "www.github.com" and "www.gitlab.com"

The `resource` key in remote url can also have a value of `www.github.com` or `www.gitlab.com`.
Currently, it checks for `github.com` or `gitlab.com` due to which the command `.ci/build.sh` when executed in terminal raises the following Exception while running the app locally
```
File "/home/kvgarg/GSOC/Coala Open Source/community/community/urls.py", line 12, in
from gci.feeds import LatestTasksFeed as gci_tasks_rss
File "/home/kvgarg/GSOC/Coala Open Source/community/gci/feeds.py", line 10, in
class LatestTasksFeed(Feed):
File "/home/kvgarg/GSOC/Coala Open Source/community/gci/feeds.py", line 12, in LatestTasksFeed
link = get_deploy_url() + '/gci/tasks/rss.xml'
File "/home/kvgarg/GSOC/Coala Open Source/community/community/git.py", line 180, in get_deploy_url
raise Exception('remote %s is not supported' % url)
TypeError: not all arguments converted during string formatting
```
This can be solved by putting an `OR condition` to check whether `url.resource` has a value of `www.github.com` or `www.gitlab.com`.
Changes need to be made in multiple files.

**Steps to re-produce the error:
clone the repo using `git clone https://www.github.com/coala/community.git`**

A `difficult/newcomer` issue .

Start in community/community/git.py, where get_deploy_url() rejects the remote URL, and inspect the related URL checks used by .ci/build.sh. Reproduce with a clone URL using www.github.com, then verify that both www.github.com and www.gitlab.com are accepted and the build command no longer raises the shown exception.
