DMD as a library package can now run through all semantic phases

In case someone wants to play with DMD as a library, it got a lot
easier as of today.
Here's an example:
```
#!/usr/bin/env dub
/+dub.sdl:
dependency "dmd" version="~master"
+/
void main()
{
import dmd.frontend;
import std.algorithm : each;
import std.stdio;
// Sets DMD's global variables. Only required to be called
once
// In the future this might be done automatically (e.g.
module constructor or initOnce)
initDMD;
// Search for the predefined import paths of your host
compiler (DMD and LDC are supported)
findImportPaths.each!addImport;
// Load a module
// (if no second argument is given, the file will be opened
and read)
auto m = parseModule("test.d", q{
void foo()
{
foreach (i; 0..10) {}
}
});
// Run through all semantic phases
m.fullSemantic;
m.prettyPrint.writeln;
}
```
Want to know what it prints? Run the file!
Spoiler: it's similar to new the AST feature at run.dlang.io:

__Warning__: the DMD DUB package is still experimental and at the
moment should only be used by alpha warriors.

Huge thanks and credits goes to Jacob Carlborg and Razvan Nitu as
well.
