modals with detached: false do not work properly in semantic-ui 2.3.1

[vbelolapotkov]

the issue is fixed in semantic-ui 2.4 so the package needs to be updated

as a workaround:

1. you can build js, css and assets with a gulp from the latest semantic npm package in a separate folder
2. copy dist to the local package and load it
3. remove atmosphere package from a project
