generated output only does relative imports

[a-morales]

If there's a .proto file that is not on a root path and it imports another .proto file then the resulting typescript file will have the import as a relative import causing typescript to throw errors. For example given the following file structure

- foo/
  - bar.proto
  - baz.proto

with bar.proto being

syntax = "proto3";

package foo;

import "google/protobuf/wrappers.proto";
import "foo/baz.proto";
...

The generated output of ts-proto would be

- google/
  - protobuf/
    - wrappers.ts
- foo/
  - bar.ts
  - baz.ts

With bar.ts being

import * from "./google/protobuf/wrappers";
import * from "./foo/baz.ts";

...

Since a relative path is specified for imports, typescript throws errors that it can't find the modules. A proper fix is to either compute the relative paths for imports when generating the output or just have them be "top level" packages (e.g import * from 'google/protobuf/wrappers') so that typescript can be configured to include the packages for module resolution.

#3 is related to this.

I'm 90% sure this is fixed in 1.4.1 / fixed while fixing #4. Going to close based on that guess, but let me know if its not.
