Merge pull request #104 from readium/feature/support_non_prefixed_page_spread_property

Support for non-prefixed "page spread" property
fixed typos to previous commit, tested working page-spread left/right/center with or without prefix properties
Merge branch 'develop' into feature/htmlInject
added support for HTML injection of annotations.css
quick-fix (no need for feature branch / pull request): SMIL Media Overlays parsing now degrades gracefully when duration metadata is missing or erroneous (edge case with some test EPUBs). Fixes https://github.com/readium/SDKLauncher-iOS/issues/35
quick fix: added missing console message forwarding for when readium-sdk errors are raised (EPUB parsing, exceptions, etc.) This error handler should be implemented in all native launchers, otherwise the console remains silent when testing erroneous EPUBs.

removed NSURLCache, added "Javascript Executor" service (benefit: main logic remains in RDServices, basic app-specific WebView code in launcher iOS)
oops, forgot to return the HTTP response (nil)
compile error
compile errors (sorry)
testing NSURLCache-free design...WIP
ah, just as with NSURLCache, the epubReadingSystem JS request from head>script needs to be unique, thus the use of a counter long
NSBundle payload is now provided as an NSData* by the app launcher (can be nil, in which case MathJax.js and/or annotations.css functionality will be disabled)
Update the interfaces for RDPackageResourceConnection and RDPackageResourceServer.
Follow-up to previous commit (https://github.com/readium/readium-sdk/commit/da10a4112d24bd5cf00b80736280b7b4b4adcb39) now SDK error handler must be provided by app launcher via a delegate (app can choose to NSLog, for example)
