[Refactor] Journalcrawler and Journal event handling

[Balvald]

Theres probably still quite the amount of duplicated code since the original event handling was just a full copypaste of the journalcrawling code, (ew I know.)

To amend this:

• Identify duplications
• Create helper functions
• Use those helper functions to replace these duplications.

Helper functions will be stored in the eventhandling.py and will be imported into respective files once thats finished.

I've decided to not do this one in the next release because, This one will probably need as much work if not more than what update v0.2.2 encompasses.

[Balvald]

ugh not sure if this stays in v0.2.5....

[Balvald]

nah it'll have to wait for another version since latest release still hasn't its bugfix #35.

Wan't to prioritize a better functioning next release than one where I get around and need like a whole week just working on this besides haven't started with it yet ....

[Balvald]

on hold for investigations concerning #45

soon™

[Balvald]

initial description changed as it changed slightly through finishing #41 #42 and #43

[Balvald]

#27 (comment) comes to haunt me again

Reason: #48

Note: I evidently already did some refactoring for event handling.
