DMD 0.163 release

This has all the new import changes in it. That breaks a lot of existing 
code (like dmdscript), the fixes are simple (adding more import 
declarations) but tedious.

I couldn't find a better keyword choice than "static import".

The renaming uses '=' instead of 'as', 'from', or 'alias' for the reasons:

1) didn't want to add new keywords, especially ones like 'as' as I use 
that as a variable name

2) didn't need to add new keywords - adding them should be done only if 
using punctuation is completely unappealing

3) using '=' and ':' is visually more distinct than embedded keywords.
