Improvements after presentation

[fincamd]

• Route parsing system now ignores routes not following JSON-LD ViadeSpec standard. Turtle files now shouldn't crash our application. (First try to fix route parsing crash #223, Bug: Route sharing feature crashing because friends and groups are not being correctly loaded #229)
• Same applies to friend group file parsing. These should now be ignored if their format doesn't follow the standard. (Bug: Route sharing feature crashing because friends and groups are not being correctly loaded #229)
• Documentation points 3 and 6.2 modified following advice from the presentation. (Update documentation (Points 3 & 6.2) #226)
• Map Search Bar Fixed (Nominatim search feature not working when the application is deployed #224)
