Just a note for anyone using flexibase - If you update bootstrap to Bas' most recent version you will need to get the latest commit from github. Its a very small change as Bas has altered the name of one of the parent less folders. I will push the update to the plugins
database shortly, but in the meantime you can either make the change manually

@import "../../bootstrap/less/bootstrap3-3-6/bootstrap";
or pull the latest version from github
