As suggested in ECM documentation.

The icon loading in the keyselectiondialog already works due
to the iconPath function. No need for custom loading.
Auditlogviewer can use QIcon::fromTheme (or the default QDialog
Button icon for close)

PimTextEdit pulls in lots of frameworks that are not needed
by libkleo in general so we make it optional. If libkleo is
used from a PIM Application it makes sense to include
pimtextedit. But otherwise QTextEdit is completely
fine for the Auditlog.

This removes dependencies which are not used by libkleo.
It also removes the extra dependency handling when
KDEPIM_ONLY_KLEO is set.

This is the beginning of revision history for this module. If you
want to look at revision history older than this, please refer to the
techbase wiki for how to use Git history grafting. At the time of
writing, this wiki is located here:

If you have already performed the grafting and you don't see any
history beyond this commit, try running "git log" with the "--follow"
argument.
