Subject: Add componentFactory pattern to always create a specific object if one is
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=0b3c59b1b8cbafcb02358ddf301d1cad3ff917bc;p=horde.git

Add componentFactory pattern to always create a specific object if one is
present, but fall back to the abstract objects without having to think about it
each time. Gets rid of a few duplicate methods also.
