Release PhD 0.4.8

Hey guys,

PhD 0.4.8 has been released! This version will probably be the last 0.4.*.
The 1.0.0, that will have the improvements of my gsoc project (

Notes:
    - Added support for external troff highlighter in man pages (Christian).
    - Added title attribute to anchor tags so address can be seen in CHM
files for external links (Richard Q.).
    - Migrated the translations from CVS to SVN  (Philip).
    - Fixed bug#49006 (The manpage format groups function arguments
incorrectly). (Moacir)
    - Fixed bug#49005 (Reference sign in function prototypes in the manpage
rendering). (Moacir)
