Note: this breaks the plugin API for editor-related document fields
and functions.
Split new GeanyEditor struct type from GeanyDocument fields sci,
line_wrapping, auto_indent, scroll_percent, use_tabs, line_breaking.
GeanyEditor::document allows access back to document fields.
Add GeanyDocument::editor field; this is only valid when the
document is valid, and NULL otherwise. This means any checks for
doc->editor->scintilla != NULL will segfault for invalid
documents - check against doc->is_valid or doc->editor != NULL
instead.
Change plugin API EditorFuncs to use GeanyEditor pointers.
Make editor_set_font() take a pango-style font string, and use a
GeanyEditor pointer.
Use GeanyEditor* instead of GeanyDocument* in editor.c (most global
editor functions still need conversion though, but this may be done
gradually or as required).
Move utils_get_current_function() to symbols.c.
Move utils_replace_filename() to document.c.
