Removed jquery, bootstrap.js, added ui.bootstrap4

[kptLucek]

Removed:

• Bootstrap dependency (theme has bootstrap included anyway)
• jQuery
• TooltipDirective (no longer required, bootstrap has it's own logic for, were using jQuery anyway)
• pooper.js

Added / replaced:

• less -> sass (scss)
• ui.bootstrap4 (for handling bootstrap logic - angular-way - https://morgul.github.io/ui-bootstrap4/)
• bootstrap 4 via package manager (scss only)
• theme from bootswatch with it's variables, "tweakable" styles, cariables may be changed once needed

I'd keep bootstrap dependency and switch to using base bootstrap scss + variables.scss from theme. That way we can modify the theme easier (I want to tweak the colors a bit, some stuff is unreadable imo). Not sure if that means that jquery has to stay, but I want to at least have css created from base bootstrap + variables. Theme can be found here https://bootswatch.com/superhero/

Already been adjusted, i've added both (and it's variables) theme and bootstrap
