Subject: Improvements if HTML is not displayed inline.
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=df76454c4d762ea3e0b23bc6e84c1328b2965d90;p=horde.git

Improvements if HTML is not displayed inline.

If HTML is only part (i.e. not a multipart/alternative part), show mime
info box allowing viewing HTML in separate window or allowing conversion
to a text/plain representation.
