rhbz1110627 zanata init

https://bugzilla.redhat.com/show_bug.cgi?id=1110627
and https://bugzilla.redhat.com/show_bug.cgi?id=1038852

Depends on https://github.com/zanata/zanata-api/pull/15 and https://github.com/zanata/zanata-server/pull/520
So what is the response to the check? If it will warn the user and ask if they want to re-enter the source directory, we should say so in the docs to make it clear. Maybe something like

```java
/**
 * Warn the user if they have selected project type 'podir' and the path
 * contains 'pot/'. If 'pot/' is present in the source directory field, it is likely
 * that the user has entered the translation directory by mistake.
 */
```
