* Make sure all source files have a LGPL copyright header, and standardize
  non-standard variations of the header to a common form.

* Check and update all copyright notices.

* Remove 'Written By:' lines. They are universally incomplete and

/**
* SECTION:st-entry
* @short_description: Widget for displaying text
*
* #StEntry is a simple widget for displaying text. It derives from
* #StWidget to add extra style and placement functionality over
* #ClutterText. The internal #ClutterText is publicly accessibly to allow
* applications to set further properties.
*
* #StEntry supports the following pseudo style states:
* <itemizedlist>
* <listitem>
* <para>focus: the widget has focus</para>
* </listitem>
* <listitem>
* <para>indeterminate: the widget is showing the hint text</para>
* </listitem>
* <listitem>
* <para>hover: the widget is showing the hint text and is underneath the
* pointer</para>
* </listitem>
* </itemizedlist>
