[FEATURE] Key rebinding

[Hoekstraa]

I feel that switching between modes is a bit jarring considering you need to use the j,k,enter and q keys.

Personally I'd like to change that to h,j,k,l, where 'h' stands in for q (except for never actually quitting) and 'l' opens posts like enter. This would make it feel more in line with vi-like behaviour.

Of course keybindings are personal preference, so it may be advantageous to make it possible to overwrite keybindings in the configuration file.

@JanSHoekstra Thanks for opening this issue.
I will take a look into it.

Yes, maybe the tab key to switch instead J and K upper keys.

Now you have the possibility to navigate with the arrow- and pageup- and pagedown-keys.

Maybe we will add some configuration options for navigation.
