Export: Add projectnameText placeholder

Description

Bugfix

What does this PR do?

Adds a projectnametext placeholder to represent the projectname in the document text - the originla projectname placeholder is now only used in the title. This was necessary, since we downsize the fontsize of projectname, if it is too long. This should not affect the normal text. But in addition XWPF read the font size of the [projectname] placeholder in the text as -1, and subtracting -4 from it caused a fontsize underflow, leading to a font size of ~32000 :/
