Shared libs

[jollyroger]

Hi. I've done some changes to the project. Hope you'll accept them. Here is the short list for every changes:

• Removed bundled hiredis and jansson sources from the project and made them available via submodules (for example if there's someone who already has installed dynamic libraries for hiredis and jansson, they don't need to download their sources and statically compile libs inside your application).

• Made possible to compile with statically and dynamically linked libraries, both bundled or system-wide installed. This is done by using shell variables USE_DYNAMIC_<LIB> and USE_EMBEDDED_<LIB>, where <LIB> is the name of the library. For example:

  USE_DYNAMIC_HIREDIS=true USE_EMBEDDED_JANSSON=false make

This will be in handy if someone wishes to package your software for some Linux distribution. For example, Debian policy denies static linking and mostly borrowing source from thirdparty libraries. Since libjansson and libhiredis is on its way to Debian (and since I'm using Debian, both these libraries and webdis) this might be me :) .

Also some note on using thirdparty libraries: it would be great if there would be some version of webdis which relies on released/tagged versions of libraries. I couldn't use hiredis v0.9.2 since you've already used changes from upstream so I just didn't have another chioce except upgrading it to bleeding edge. Also there is no way to get webdis packaged until it relies on released library versions.

Anyway, thanks for your software and good luck in all your projects!

Hmm, It seems i've forgotten that jansson has to be configured first. Will send new pull request once this is fixed.
