Several other minor bug fixes, some of them localization-related.

Plugin control

Settings saved in xml file in the plugin Startup Maxima commands can be customized Regular expressions for translations can be added (for testing purposes)

Third party GPL2 Maxima code for handling of negative exponents and exponents of exponents replaced by internal solution -> License issues avoided.

Compatibility to plugin interface changes

More verbosity in assumption messages (expression with assumed restrictions is specified)

Graphic functions

New functions Draw2D() and Draw3D() for convenient plotting. - Maxima package draw is loaded automatically - file type identified by file name extension (none means svg, png means png) - Gnuplot preamble commands can be supplied without conflict to internal settings.
