Add -k/--key option. Allow getting more properties of the app

[ryanluoo]

Now by using -B and -j options together, we can get some basic properties of the app. Like CFBundleVersion.

But actually more properties could be output by passing the corresponding keys.

We can find all the existing keys in Apple's doc

So I add a new option, allowing people to get more properties. If multiple keys are needed, we can join them by '&'

For example, if we need UIFileSharingEnabled, CFBundleExecutable, CFBundlePackageType of the installed app.

UIFileSharingEnabled specifies whether the app shares files through iTunes
CFBundleExecutable identifies the name of the bundle’s main executable file
CFBundlePackageType identifies the type of the bundle and is analogous to the Mac OS 9 file type code

We can use the command :
ios-deploy -B -j --key=UIFileSharingEnabled&CFBundleExecutable&CFBundlePackageType

Part of output:

"com.kingsoft.www.office.wpsoffice" : {
    "CFBundleShortVersionString" : "11.3.1",
    "CFBundleIdentifier" : "com.kingsoft.www.office.wpsoffice",
    "UIFileSharingEnabled" : true,
    "CFBundleDisplayName" : "WPS Office",
    "CFBundleName" : "WPS Office",
    "CFBundleExecutable" : "wpsoffice",
    "CFBundlePackageType" : "APPL",
    "CFBundleVersion" : "11.3.191809"
  },

Also revise the error message. Seems we missed some required options before

on_error(@"One of -[b|c|o|l|w|D|R|X|e|B|C|9|] is required to proceed!");

May I ask how often did you release a new official version to HomeBrew ?
My project is relying on ios-deploy now . Really appreciate it if I can experience the new feature from the official HomeBrew release.

Thanks for the PR! Will try to make some time today to take a look.

As for release schedule, it's pretty much ad-hoc. We haven't done a release in a while so I can get a new release going after this PR lands.
