Handling Απαλλαγές Μαθημάτων

[sakrifor]

There are cases where there are Απαλλαγές Μαθημάτων where some have grades and some do not. This case must be resolved in both PDFParser and HTML Parser. In the latter case the issue has been resolved with a hot fix 5452a7c which should be refactored. Cases where the grade of these courses is not specified should be assigned with 5. This matter is open to discussion.

First of all:
Do you know how Course Exemptions actually work for our uni?
Has the student taken the course/examination, and why are they listed separately?

Fixes:
We properly detect them now in HTML & PDF parsers in commits ecfc7d2 and 6df340e respectively.

Missing grades:
We still have to decide what to do with those that don't have a grade.
For now, the csv with the results will just have a blank grade, like so:

NCO-01-05, ΒΑΣΙΚΕΣ ΑΡΧΕΣ ΠΡΟΓΡΑΜΜΑΤΙΣΜΟΥ, Υ, 2018 - 2019, ΦΕΒΡ, 9, 7, 9,

P.S. How come some of them have a grade and some do not?

@din0s I have no idea, let's consider this resolved for now.
