implemented "format" file and expression parsing as well as application to the transcript

 * "formats" are regular expressions encapsulated in Pango markup that allow the description of powerful highlighting rules
 * highlight as you type via entry boxes
 * loading from files implemented and tested but cannot yet be done via the UI
 * transcript widget is built as libtool convenience library
 * some renamings were necessary
 * install transcript widget header
