support bad applications for release

```
{application, ____,
 [
  {description, ""},
  {vsn, git},
  {registered, []},
  {applications, [
                  kernel,
                  stdlib
                 ]},
  {env, []}
 ]}.
```
If no modules specified - should add one.
If version is not a string - should add one (in case of git take app.git_vsn)
