    Define couch version

    This changes the way we set the value for `couch_server:get_version`. The 
`get_version` function is used in:
    - version key of welcome message
    - Server header returned in every response
    This implementation defines a COUCH_VERSION macro. This is done in order to 
ensure that we keep using `{vsn, git},` in `src/`. There is also 
additional benefit of using the macro. It saves us an access to ets table. ETS 
is used for `application:get_key`. Since get_version is called for every 
request the saving should be significant. This would improve on previous 
analysis and work done by @robertkowalski
