Description:
------------
the current release of PECL_Gen, as well as the current CVS version, do reference non-existing functions because the studlyCaps conversion was not completely done in Extension.php and License.php.

Recommended fix:

1) Extension.php, line 971: replace
  $code.= $this->license->license_comment();
by
  $code.= $this->license->getComment();

2) License.php, line 77: replace
  fputs($fp, $this->license_file_text());
by
  fputs($fp, $this->license_getText());


Reproduce code:
---------------
pecl-gen any.xml

Expected result:
----------------
no error

Actual result:
--------------
error that function license_comment() was not found / that function license_file_text() was not found
