Grive git version

Grive is still considered experimental. It just downloads all the files in your google drive
into the current directory. After you make some changes to the local files, run grive and
it will upload your changes back to your google drive.

There are a few things that grive does not do at the moment:
- wait for changes in file system to occur and upload. Grive only sync when you run it.
- create new files in google drive. Grive only uploads changed files that already
  exist in server.
  
Of course these will be done in future, possibly the next release.

This is compiled in Fedora 16 x64. You need the following libraries to run:
json-c, libcurl, libstdc++ and openssl. CppUnit is also optional and required
only if you want to build the test cases.

When grive is ran for the first time, you should use the "-a" argument to grant
permission to grive to access to your Google Drive. An URL should be printed.
Go to the link. You will need to login to your google account if you haven't
done so. After granting the permission to grive, the browser will show you
an authenication code. Copy-and-paste that to the standard input of grive.

If everything works fine, grive will create a .grive file in your home directory.
It will also start downloading files from your Google Drive to your current directory.

For Ubuntu/Mint 11.10 users, go to build directory and run 'cmake ../' from that particular directory


Enjoy!
