Bump version number and label.

Version was 0.1, which was a bit misleading, since much of the
module contents is stable and unchanging. Changed to 1.0 to
reflect that.

Bump version number and label.
Install header-only pkgconfig file to generic lib/

The previous version assumed that we had libraries, and thus always
installs the .pc file in the multi-arch library directory. However,
we now have modules which does not have a library, but whose header
files still need to be located. Since the lib/ directory is usually
in the pkgconfig search path, it is natural to put them there.

Synchronise build system with opm-core
update packaging
use a fully qualified url for source0
remove invalid entries from Doxylocal file
Merge pull request #87 from akva2/remove_invalid_doxy_entries

remove invalid entries from Doxylocal file
make packaging compatible with EL5
Specify dir. layout and stylesheets in common templates

These options should be common to all OPM modules to get the same look
for the generated documentation.
Only add option for shared libraries once

The way the test was done previously, it was added for *every* option
after `--enable-shared`, not only that one.
Allow to search for multiple libraries in package

Some packages are split up in several library files, where each of them
doesn't have their own CMake find-module. So we cannot put this list in
the prerequisites. Unlike the headers, where we just add the directory,
all the libraries must be explicitly named on the link line. Thus, we
should allow to specify more than one name in the lib parameter.

The first name specified is designated as the "primary" library and is
assigned to the _LIBRARY variable; the others occur in _LIBRARIES as if
they were prerequisites.

Note that the build system cannot replicate this setup itself; it always
assumes that we are building (at most) one library from the source
files.
