SQLite3 Phobos branch

[Jesse Phillips]

I have a branch of Phobos which includes SQLite 3.7.5 and its bindings 
for D. I have updated the posix.mak to include this when building.

I am posting here at this time to prevent duplicate effort and give a 
heads up that I won't be able to test this for Mac or BSD. I would also 
like to know what I would need to complete to get this ready for a Pull 
Request.

I will work to get this done for Linux and Windows/Wine this weekend.

On another note. The source distribution uses autotools, but it compiles 
fine just by calling GCC. So there might be some interesting flags which 
should be set.

The binding effort can be attributed to Alexey Khmara, I just added a few 
lines for the update.
