Bug fix, unify error reporting

From @smilediver:

• Unify error reporting (#134)

From @Incont:

• Fixed --exists not working (#131)

Bug fix for #129 - ios-deploy -c never returns

1.6.1

Added --uninstall_only, --mkdir, --rm options

From @luser:

• Added --mkdir and --rm options (make directory on device, remove file or directory on device)

From @mikelupo

• Added --uninstall_only option (uninstall an app only, by bundle_id)

New "exists" feature, lldb bug fixes.

Thanks to our contributors @urklc and @dot-asm!

from @urklc:

• (-e, --exists) check if the app with given bundle_id is installed or not

from @dot-asm:

• allow to pass command line arguments from (lldb) prompt;
• make lldb exit as opposite to relying on kill (which is problematics
  because it messes up tty settings);
• handle event timeout in autoexit_command to avoid endless loop;
• use dynamic TCP port and listen on localhost (no need to expose the
  port to Internet);
• close accept socket once connection is established;

Bug fixes

• return code for --version is zero, instead of non-zero for success (#105)
• fixed model name detection and crashes (#90, #91 )
• readme updates (#92, #94)

Bug fix for 1.3.1 :/

Re-fixes #80 --detect not showing non-zero exit code when no devices are detected (--debug is implicit when you set --detect to prevent SIGSEGV

Bug fix

• Fixes #80 --detect not showing non-zero exit code when no devices are detected.

Bug fixes

Thanks to @senthilmanick, @eddieh and @CSOscarTanner for contributing to this release.

• added --download option
• when the device is locked, the python source prints and exists. The server sees this as an empty packet. We are using this to exit out of the connection
• when we use --justlaunch, we need to do safequit and detach. Otherwise we could hang forever
• fixed problem with the parser of the value of the parameter -i
• fix for mismatched SDK build numbers
• allow the symbols and the disk images to be in different DeviceSupport directories.
• fixed python script for lldb launch
• fixed #37 AMDeviceValidatePairing fails when uninstalling
• fixed #74 SIGSEGV-ed while listing the sandbox of an application on iOS8

Xcode 6 Fixes

• Fix lldb status checking
• Fix AFCFileRef[Read|Write] prototypes
  Incorrect AFCFileRefRead prototype was causing crashes in 64-bit build when reading large files.
• Handle no --args
  When no --args are passed application was started with {args} as argument instead of no argument.
• Fix usage semantic and pair of resource leaks
  AFCConnectionOpen and AFCFIleInfoOpen don't require initialized pointer to pointer to result, but do require corresponding Close calls.
• Arrange callback in read_dir for future use
  Custom callback is called for every file or directory listed on device. This will be used for file download.

Bug fixes

• Fixes #51 - When the device is locked, ios-deploy hangs.
• Fixes #52 - Enhancement: Add "Just launch" option
