CLIMATE-406 Please create a DOAP file for your TLP

Hi Folks,
Please see new file which addresses 406 and (nearly) gets us on projects.apache.org.
All we have to do once this is committed is the following
checkout 
```
https://svn.apache.org/repos/asf/infrastructure/site-tools/trunk/projects/files.xml
```
add the following entry
```
<location>https://git-wip-us.apache.org/repos/asf?p=climate.git;f=doap_CLIMATE.rdf;a=blob_plain;hb=HEAD</location>
```
