[useblocks#66] remove 'display: inline-block' from inline code blocks (…

…useblocks#80)

inline code blocks should not be assigned 'display: inline-block'
despite their namesake. without 'inline-block'.

Setting display to 'inline-block' turns <code> into a block element,
which when applied to an exceptionally long element (i.e. long
non-breaking 'pre'-formatted lines) makes ordering and sizing of
elements around it weird.
