Workarround for http://savannah.gnu.org/bugs/?46756 (discussion https://mail.gnome.org/archives/gnumeric-list/2015-December/msg00026.html)

This installs a bunch of icons via gresource.  In the process we rename
the icons to something consistent.

Not everything is done yet.  And we want to keep installing our application
icons.

There are three standards compliant ways of getting the tag field
for a union like GnmValue.

1. Via the subtype struct that the value has.  That only works (and
   is utterly pointless) when we already know the value type.

2. Via another union member that is a structure having one or more
   initial members matching the actual struct type.  The silly thing
   is that this rule only applies to structs; I guess that is an
   oversight, but a fat lot of good that does us now.  In practice
   this means we should use ->v_any.type for that.

3. Using the pointer-to-first-struct-member rule.

To simplify matters, define VALUE_IS_ARRAY and VALUE_IS_CELLRANGE
macros.

Eliminate some hacking workarounds.

That way we don't ask translators to deal with them.  We aren't going to
show them, so there is no point in confusing translators and giving them
extra work.

Use link-color instead of a hardcoded blue.

Evidently introspection is picky.

We were unconditionally looking of untranslated function name for the
purpose of displaying help texts.

This isn't ready for prime time yet.  When turned on, function names
ought to be translated in the gui.  That, of course, requires that
translators have translated the function names.  The place to do that
is in the help text.  For example:

msgid "PRODUCT:product  of the given values"
msgstr "PRODUKT:produktet af de givne værdier"

(Does that really have two spaces?)
