Bug 361368

In Kontact Mail 3.5 it was possible to delete the 
text/html alternative attachments in multipart/alternative emails.
For example by using the context menu in the view that show the email structure
on the text/html alternative and choose "delete attachment".
Kontact Mail 4.14.10 misses this function.
Because it is a functional degration without catering the use case differently I consider it a bug.

Use case:
Often the size of the text/html alternative part is very large compared to the text/plain part
that contains all information. The reader of the email wants to keep a record of the email
in a space saving way.

Scenarios that illustrate the use case:
There is a quota on the email folders when using imap.
Some emails may be required to be kept for archival purposes by tax law.


Reproducible: Always

Steps to Reproduce:
1. look at an html email that is send as multipart/alternative
2. try to delete the text/html branch including the image attachments.

Actual Results:  
Found no way to do it.
