Fix cycle counting for relative branches.
The original creator of the cycle counting code appears to have mangled two
different approaches to counting the cycles for relative branches into the
final product which led to counting too many cycles for the branch
instructions. The comments in the cycle table were correct but the code was
doing some incorrect things.
Also add the missing LBRN entry to the cycle table. The one labelled LBRN
was not, in fact, LBRN, but one of the actual useful branch instructions.

With LWTOOLS 4.0, a substantial reorganization of the project has occurred. This document serves to explain the reasoning behind the various changes. The most obvious change is that the gnu auto tools have been eliminated. While they proved useful for initial distribution of the software, particularly for construction of the win32 binaries, they have since proved to add an unacceptable level of complexity to every aspect of development from merely tinkering with source files to doing complete releases. Thus, the auto tools have been ditched in favour of specific hand tuned help where required. The other substantial change is that the source code repository has been recreated from scratch. The old repository was full of cruft from various revision control systems that were used over the years (CVS, Subversion, and Mercurial). It was felt that starting a new Mercurial repository with a completely clean slate would simplify matters substantially. Thus, the old repository now serves as an archive.
