Kore applications now get a build.conf which may contain different
build flavors. Each flavor can get its own cflags or ldflags.
This was in parts inspired by #106.
A new cli command has been added:
kore flavor
This command allows you to see all flavors and switch between them.
The kore build command now also takes a -v argument which if given
dumps the used CFLAGS and LDFLAGS out to stdout.
For existing applications the build.conf is automatically generated
next time you run kore build or kore run.
Also fixed a bug in the json_yajl example, sneaky change here.
Semantics for using pgsql API have changed quite heavily
with this commit. See the examples for more information.
Based on Github issue #95 by PauloMelo (paulo.melo@vintageform.pt)
with several modifications by me.
