tex-standalone{,-doc}: update to 1.3a

Bug fix update:
---------------

Fixed compatibility issues with LuaTeX which arised after \ 
non-backward-compatible updates to LuaTeX.

Config file:
 * Fixed log file warnings when used outside preamble by wrapping \ 
\PassOptionsToPackage call into preamble check.

Package:
 * Added check if \sa at requestedpage is undefined or empty, which can happen \ 
with newer versions of LuaLaTeX.
 * Updated page handling to new graphics driver version.

Also fixed the following reported bugs: (see \ 
https://bitbucket.org/martin_scharrer/standalone/issues)
 * Issue #22: Removed processing of AUX file with \globaldefs.
 * Issue #25: Changed how papersize special is added for dvips.
 * Issue #26: Adding '-units PixelsPerInch' to 'convert' call so that generated \ 
PNGs have correct units parameter.
 * Issue #30: Replaced jobname with subjobname in DVIPS precommand.
 * Issue #31: Added \makeatother before inputting .sta files so that the \ 
subpreamble-changed test works with files
using \makeatletter.
 * Issue #40: Corrected order of border option in manual.
