examples: warzone2100 <3.0: do some enhancements

Use all commands without multilib support, better document adaption
as well as discovery and add the maintainer.
TODO: update for 0.2.0 release
examples/README: update additional info
doc: statmem: do an update and show PIE

Our ASLR/PIC/PIE support patch set for scanmem has been accepted
and merged upstream. So we can show it here to show how PIE works
and in which region as well as region type the match is located.
maps: fix null termination in code regions detection

The binary name used to detect the regions belong to the same ELF
binary should better be null terminated just in case the strcmp is
used instead of strncmp.
maps: introduce parse_region() to reduce line length

Functionality is still the same but we can reduce the line length
and improve readability by moving the region parsing into a
separate function.
examples: warzone2100: fix a comment about PIE
README: do a minor update
libmemhack: PIE: support multiple code offsets

For now we send for all configured dynamic memory classes the same
code offset. But this is a PIC preparation.
libmemhack: fix debugging compile

Commit 08099042 "linuxhooking: add debug output to file possibility"
introduced new debug outputs which break the compilation.
So fix them.
adapt: get rid of bashism

We call so simple functions to adapt code addresses. There is no
need for bash specific shell code.
doc: dynmem: update dynmem hacking and show PIE
doc: dynmem: update dynmem discovery and adaption
doc: dynmem: move LD_PRELOAD alternative to known issues
AUTHORS: add code inclusions
options: add '--version' support

We show the app name, the version number and the date/time of the
build. Also the email address for bug reports is imporant and
displayed.
options: add a secret command line option

It shows why ugtrain 0.2.0 is the Dietmar release.
Changelog: update for 0.2.0 release
adaption: add the missing common template include

Commit 91a2771f "ugtrain: move more adaption code where it belongs"
introduced a build bug. The "commont.cpp" include for the
to_string() function calls has been forgotten. So add it.
Release 0.2.0
