Rethink doom-initialize & use package-initalize

Browse source 
Doom saves a lot of startup time by avoiding package-initialize, because
it loads every packages' autoloads file, which is expensive.
Unfortunately, these autoloads files are necessary for some plugins with
abnormal file structures (such as ESS). Previously, I was content with
loading them myself, but these occurrences have become more frequent, so
it would be safest if I relied on package-initialize more.

So doom-initialize will now do so. However, it will cache the load-path
(and Info-directory-list, fixing the lost info buffers) on first run.
This makes byte-compiling Doom almost useless, but it makes startup just
as fast as Doom would be if you had.

This needs more testing.
