A lot of new properties are added, which are going to
be the basis of the coming configuration replacement.
Also a little cleanup is done in a few places.
Based on the implementation of localization via Gettext
contributed by Enrico Tröger, a few adjustments were made
to allow Midori to be properly localized. Initially
German is fully supported.
The 'browser' struct is superseded by MidoriBrowser, which actually
represents a window that holds pages, i.e. tabs. The tabs are currently
of the type MidoriWebView, which is a slightly enhanced WebView. Also
MidoriWebSettings is introduced to hold additional settings that Midori
needs.
The other two new classes are MidoriTrash, representing closed tabs and
windows and MidoriPanel, representing the side panel.
The refactoring allows for several features to be much more easily
implemented, such as full support for multiple windows and instant
saving of modified files, such as bookmarks or the session. Regressions
are expected and not everything is done yet.
