Merge lp:~saiarcot895/libopenshot/qt-json into lp:libopenshot/0.0

[Saikrishna Arcot]

Switch from using JsonCPP to Qt Json.

Some things to note:
1. Qt 5.2 is required for this patch. If Qt 5.1 compatibility is needed, I can provide it.
2. The final JSON output with this patch is likely not compatible with the JSON output in the current version. This is in part because integers are being stored as literal integers instead of being converted to strings.
3. While none of the tests (I only found one) involving reading/writing JSON seem to have failed, there may be errors in the patch.

On another note, I found that the video length was being stored in "long int", which is 32 bits on Windows and 64 bits on Linux/Mac. Because of this, the lines that read/write the video length might not compile or work correctly on Windows.
