Fix macro security UI usability problems

* Don't hide the option dialogs "Macro security" push button.
I don't see any reason, why these settings should be hidden, if
macros are disabled or settings locked. At least a user can now
check, what is going on (still nothing shows disabled macros for
a document in the UI AFAIK).
* Don't scale the lock icons of the trusted list boxes.
This just uses the same alignments, which the macro security
level lock image uses, otherwise the image is scaled to fit the
whole space of its layout cell.
* Don't disable the trusted list boxes.
If the setting is locked, it's sufficient to disable all the
buttons, which allow modification (so View can stay enabled).
This way you can still scroll the list. Correct button handling
is already implemented and works for me.
* Catch exceptions of broken certificate data.
If your config contains certificates, which can't be correctly
decoded, the NSS backend will throw an exception, which kills
the dialog, but not the nested loop, resulting in a locked LO.

Since we don't want a string change in LTS, this drops the whole
"broken certificate" warning dialog. There already are SAL_WARNs,
which log the same warning, and are considered sufficient for
debugging broken configurations.
