Added "export/export/latex/arabic_simple_pdf4_systemF"
and "export/doc/ar/Intro_pdf4_systemF"
to the list of tests which ignore "missing glyph" error.
Thanks to Jürgen Spitzmüller.
New file: ignoreLatexErrorsTests
The sublabels in this list of export-testnames specify which error
messages should be ignored.
For each sublabel (for example "xxx") the lyx-command line is expanded with
"--ignore-error-message xxx"
