Missing method for OmegaT 3.0+ IFilter interface

[Hiroshi Miura(Tokyo Northside)]

OmegaT 3.0.8 and later ask an interface method

/**
  * Returns the encoding of the last parsed source file.
  * @return the encoding of the last parsed source file, or null when no file has been parsed yet. 
  */
  String getInEncodingLastParsedFile();

 It is not implemented in Okapi filters for OmegaT.

When drop OmegaT stub and use OmegaT 5.5.0 from MavenCental, this causes a compile error.

I’ve attached a patch, which add the method to AbstractOkapiFilter.java

Hi Hiroshi.

Thank you for all the contributions, but they would be a lot easier to accept if they were Pull Requests rather than patches.

cheers,
