Tabular version as a paramter

[andrestelex]

We should make Tabular version font independent. So a custom parameter like Tabular = True should be enough to fix widths in a particular font.

Maybe it would be useful to have an option to specify the width of the characters. So paramTabular = 380 would set the width to 380 and center the shapes.

Adding the width value could be optional, but please not required. If you work on unitized typefaces: you want to keep each glyph advance width independent, and you want to run the macro in tabular mode so it optically center each drawing into his own advance width (but not changing it).
