Convert to arrow functions and remove .bind()

[Libens-bufo]

Description of change(s), including why:

Converted arrow functions in various frontend pages to arrow functions which do not have their own 'this'. Therefore, the arrow functions will point to the 'this' of their lexical scope, in this case the component. So the .bind functions become unneeded, and were removed. Some callbacks in render functions containing .bind method to pass in arguments were changed to arrow functions returning the needed function with args.
