Several under-the-hood changes and changes to the build system, including a cleaner way to compile the examples and documentation.

Memoize (1.0.0 --> 1.1.0):

Improve the extraction scripts:
- respect TEXMF_OUTPUT_DIRECTORY;
- respect openin_any and openout_any;
- implement --format;
- improve error reporting;
- drop the Path::Class dependency for the Perl script;
- allow for PDF::Builder in the Perl script;
- implement --library in the Perl script;
- set an appropriate exit code on exit;
- and several further minor changes.
Remove key path in favour of prefix.
mkdir is now initially true, but the directory is only created if mkdir command is non-empty (and it is empty initially). The definition of (no) memo dir is accordingly simpler.
The directory name is now appended to the value mkdir command when
constructing the system call.
A workaround for compatibility with package morewrites.
Process package options using the new LaTeX mechanism to avoids the issue of
spaces in package options. The remaining issue of / is addressed by
implementing option options.
Add the missing commands to nomemoize and memoizable, and implement a
generic variant of the latter (memoizable.code.tex).
Implement auto-key to context.
Write a c-memo even upon abortion.
Demote warning messages "memoization aborted" & "marked as unmemoizable" to
info messages.
Implement biblatex support.
Support \DiscardShipoutBox.
Advance the counter underlying \pgfpictureid when utilizing a tikzpicture
(memoize tikz).
Remove the \pgfsys@getposition hack for tikzpictures.

Advice (1.0.1 --> 1.1.0):

Implement \AdviceCsnameGetOriginal.
Change \AdviceGetOriginal to expand to the internal control sequence
holding the original definition of the advised command under full expansion.
Add the missing info messages for environment (de)activation.
Add the original command meaning to trace.
