applies a uniform formatting across source files, removes tab characters, whitespaces, and removed unused imports

- [ ] review changes with Karl

## motivation

I had to deal with a pull request recently on a file with some truly bizarre formatting that made the diff very difficult to understand.  

Looking at the project as a whole, I identified these issues:

* Xcode project says indent 4 spaces, but some files have tab characters (\t) and different indent settings
* there was whitespace everywhere (newlines and trailing spaces)
* there was no formatting convention follow - every file adopted its own convention or multiple conventions

## strategy

This pull request has _no_ semantic changes.  All the changes are to the formatting.

Because they were 3rd party or submodules, I did not touch these directories:

* Classes/CocoaAsyncSocket
* Classes/CocoaHttpServer
* Classes/JSON 
* LPCDDataScanner.*
* calabash-js/               

###### important 

- [ ] LPQueryAllOperation.m contains tab characters and inconsistent formatting
  - I did not touch this file in case you want to merge pull request https://github.com/calabash/calabash-ios-server/pull/30

## what i did

- [x] tabs ==> spaces
- [x] reformatted all the source files using AppCode
  - indent 2 spaces 
  - wrap to 80 characters
  - uniform spacing between method bodies
  - `- (void) play:(NSArray *) events` signature style
  - 'smart' argument wrapping
  - manual formatting
- [x] stripped trailing whitespace in _most_ of the files
- [x] removed unused imports

- [x] Xcode project indent is now 2 (was 4)
- [x] Xcode project Organization is now Xamarin
- [x] Xcode project Class prefix is now LP

## questions

- [ ] copyright at the top of source files
      * LessPainful ==> { Xamarin | remove } 
      * +1 to remove (hard to maintain, ambiguous meaning, visual clutter, opaque to Xcode refactoring, generally useless)
      - [ ] Trevor Harmon - LPExitRoute.h/m copyright
      - [ ] Jim McBeath - LPAppPropertyRoute and LPLogQueryRoute
- [ ] modernize objc.

## bugs

- [ ] LPEnv.m `[super dealloc]` must be called _last_
- [ ] LPJSONUtils call to `respondsToSelector` is made on `result` and not on `object`
- [ ] LPReflectUtils is missing a return in `invokeSpec:onTarget:withError` and the default switch case is not defined
- [ ] LPUIAChannel [super dealloc] should be called _last_

## analysis

- [ ] should suppress unused variable warnings in LPSetTextOperation with __unused
  - [ ] similar problem in calabash-js/CalabashJS/LPWebQuery.h
  - [ ] why are these not extern'd or in the .m file? 
  - [ ] should i just fix this?
- [ ] fix or suppress unused variable warnings in calabash-js/CalabashJS/LPWebQuery.h
- [ ] should suppress undeclared selector warning is GCDAsyncSocket and LPHTTPServer with clang diagnostics push/pop
- [ ] LPSetTextOperation.h the static variable should externed or moved to the .m
- [ ] LPDebugRoute. result dictionary is never used
- [ ] LPGenericAsync suspicious conversion of UInt64 to -1
- [ ] LPKeyboardRoute missing dealloc method and `_events` ivar is not released
- [ ] LPLocationRoute missing import of UIAutomation.h 
- [ ] LPQueryLogRoute has 2 suspicious unbalanced retains
- [ ] LPScreenshotRoute2 remove or change the name?
- [ ] MKMapView+ZoomLevel.m suspicious conversion of double to NSUInteger 
- [ ] LPRecorder dealloc does not playbackDelegate but it retains it
     - this is a singleton and dealloc is never called, but...
     
## recommendations

- [ ] drop iOS 4 support and bump min version to 5.1.1 to compile for x86_64
- [ ] turn on verbose warnings
- [ ] update 3rd Party Sources by building them as .a?

## tests

Since there are no semantic changes, I did not run an exhaustive test suite.
