Update style packages dependencies

[allyoucanmap]

Description

It would be nice to update following libraries:

• update bootstrap to 3.3.7 the latest supported version of react-bootstrap. This update will help the geonode-mapstore integration
• and less language to 4.1.1 to support map functionalities. This will help in the creation of for loop for theme variants

What kind of improvement you want to add? (check one with "x", remove the others)

• Minor changes to existing features

@allyoucanmap there are some style problem:

• The toc toolbar and the search layers bar are moved up
  

• The color of the family font on visual editor is lighter
  

• The close button in the save changes pop up and the delete button in delete pop up are moved up

@ElenaGallo thanks, I'll work on it

@allyoucanmap Looks like degrading less lib to 3.13.1 seems to work

[allyoucanmap]

@dsuren1 I would prefer to keep latest version of less, the issue is due to computation of variables not included in parentheses, working on it

[dsuren1]

@allyoucanmap Yes that's right, seems like it's also affecting some styles (scss) conversion from other libraries as well. I just came across one.
Ex. NumberPicker from react-widgets

We can just override those classes, however, not sure how many such similar libs have impacted.

@dsuren1 just checked and it seems react-widget is not included in the main theme but included directly in the components. The library has an issue with the computation of the buttons. Just tried to add it to the main theme with the overrides and it solve the issue:

@import 'react-widgets/lib/less/react-widgets.less';
.rw-numberpicker {
    .rw-btn {
        height: (@input-height / 2);
        line-height: (@input-height / 2);
    }
}

I would like to use a version of less greater or equal than v3.5.0 to be able to use map functionalities for theming pourpose so I would prefer to fix the style
