Bug description: ghc fail to regognise option if more than one option are entered in "Extra compiler options" fiels (separated by space).

Solution: change addExtraOptions function of CompilerParams class in package de.leiffrenzel.fp.haskell.ghccompiler:
----------------------------------
  private void addExtraOptions( final List list ) {
    if( preferences.getBoolean( USE_EXTRA_OPTIONS ) ) {
      String extras = preferences.getString( EXTRA_OPTIONS );
      if( extras !=  null) {
          String[] opts = extras.split(" ");
          for(int i = 0; i < opts.length; i++) {
          if( opts[i] != null && !opts[i].trim().equals( "" ) ) {
            list.add( opts[i] );
          }
          }
      }
    }
  }
----------------------------------

Sorry, I'm not so good in Eclipse plugins (and in Java programming at all)), so this code must be additionally checked for errors.
