Update to CLN 1.3.0.

Changes since previous package:

2009-06-30, version 1.3.0
* Use the GNU autotools as build system.
* Implemented a more portable module dependency mechanism.

2008-04-05, version 1.2.2
* Re-establish CLN-1.2.0 ABI and fix ARM build, both inadvertently broken in
  the previous release.

2008-03-24, version 1.2.1
* Fixed some bugs in the output of numbers larger than 2^32 decimal digits.
* Modifying C/C++ operators like +=, ++, etc. are now enabled by default.

2008-01-19, version 1.2.0
* Save big amounts of memory in computation of some functions and constants by:
    - Avoiding pre-computation of series terms and instead computing them in a
      streamed way.
    - Avoiding computation with excess precision in binary splitting algorithm
      by coercion of intermediate integer values to floating-point as early as
      possible.
* Added support for huge numbers:
    - intC used for all counter loops.
    - intE is now a 64-bit type on all 64-bit platforms and even on selected
      32-bit platforms.
* CLN now uses C++ exceptions for error handling. The cl_abort() hook is not
  supported any more. Please refer to the documentation to learn about existing
  exception types.
* Fixed a bug on i386 where comparing Z/2Z ring zeros returnd random results.
* Removed cl_boolean. Use built-in C++ bool instead.
* Dropped the cln-config script. Please use pkg-config instead.
* Updated infrastructure to that of libtool-1.5.24.
* Changed encoding of all files to UTF-8.
* Fix compilation issues with GCC-4.3.
* Fix linking issues on platforms that don't feature weak symbols (like win32).
