Adding "School' s name" "static text" ability to change

[kdrosos]

In FET there is "School's name", where the school' s name appears in the final .html files.

Maybe the text "School' s name" can be parametric and thus to allow changing to "Department's name" or "Institution' s name" and etc.

This can also allow a "School' s name field" as:

"Faculty of FET: Department of FET"

[Liviu Lalescu]

In English, the title is "Institution name". Maybe the Greek FET translates it as "School name".

There can be many output templates done, but it is not in my expertise. Maybe in the future. I'll add in the TODO.
