Implement global symbol renaming

[GoogleCodeExporter]

There have been a number of requests from third-party integrators to support 
renaming / prefixing the PLCrashReporter's global symbols (including class 
names), as to prevent conflicts when users link multiple libraries that 
incorporate PLCrashReporter.

Many of the libraries incorporating PLCrashReporter do so in combination with 
other functionality; analytics, beta distribution, etc, and as such, it's 
possible that users may not use the crash reporting functionality at all.

To support this, we will offer an optional #define that will prefix all 
globally defined symbols, to be used by integrators when building the library.

As an alternative to this, we could try rewriting the symbols in the release 
binaries, however, this would be unduly fragile.
