RoundCube 1.6.9 - 1.5.9

[Erulezz]

Updates 1.6.9 and 1.5.9 released
These are immediate service releases to fix regressions introduced in the most recent security updates. Both releases contain two following fixes:

• Fix regression where printing/scaling/rotating image attachments was broken ()
• Fix regression where HTML messages were displayed unstyled ()

These releases are considered stable and we recommend to update all productive installations of Roundcube with these.
