Feature/New OSF Navbar Changes [EOSF-660]

[pattisdr]

Purpose

Fixes a few issues found with the new navbar styles during the OSF-side implementation. Also incorporates latest feedback from product.

• Modifies placement of sign in and sign up buttons in new navbar and positioning/width of auth dropdown. Placement/width of sign in/ sign up buttons were uneven and auth dropdown width was dependent on length of user name.
• Modifies location of current service name
• Modifies location of caret
• Size/position tweaks on osf-logo/current service name font
• Drop 'OSF' on mobile view
• Moved bootstrap back to dependencies instead of devDependencies. Preprints and Registries rely on this being in dependencies.

Changes

Above changes made to sass/_bootstrap.scss, and then the results of npm run gulp sass were committed.
