Fix bad interaction between pluggable InputTypes and Microsites

This reverts commit eb9133ae.

ORA-352

Pluggable InputTypes use edxmako.paths.add_lookup to inject new
mako template directories. Those were getting clobbered by microsites
(and by theming), which were completely rebuilding the mako template
lookup list from scratch.

This commit switches those two features to use the same add_lookup
function as pluggable InputTypes.

Translation fix in studio: For better translation in unit.html

Make paver respect NO_PREREQ_INSTALL

As the sentence in unit.html is splitted into three parts due to the varible release_date may be None, it breaks the integrity of a sentence.
Different language may have different word or event grammer order, so if a sentence is breaked into three parts, translators cannot adjust the word orders to create a good translation.
So this fix tries to combine the sentence together.
