Added Save function to ParticleEmitter, which dumps the parameters as XML. Added menu items to editor to load/save ParticleEmitter parameters. Closes #51.
Fix crash on empty file name.
Fix editor toolbar not resizing and ui re-layout values after resize.
Enhance toolbar editmode select icon.
Added emissive shader variations to LitSolid shader. Default emissive modulation color to white, similar to environment map color.
Add pixel & time threshold for sending a drag begin UI event. Closes #65. Removed code duplication between mouse & touch hover.
Drag-related code cleanup.
Added generated event list documentation page. Closes #66.
Fixed false positive bug in String::EndsWith().
Check font's OS/2 info for possibly larger ascender & descender values. For safety, verify each font glyph's width & height against the actual glyph bitmap width & height. Use the maximum of specified row height or the ascender + descender.
Change the LineEdit elements in the file selector & console to match the height of other LineEdits in the editor. Remove hardcoded adjustment code from FileSelector.cpp & Console.cpp and rely on the style instead.
Fixed erroneously removed script API function.
Close Windows gap. No pun intended.

- Fix document build on Windows platform as Windows "shell" failed to perform the file name expansion (globbing) as expected.
- Refactor batch files to they can be invoked from any directory (similar to their shell script counterparts).
- Sort header files for generating event list so the output remains the same accross different scandir implementation.
Only copy file serialization attributes when cloning a node hierarchy. Fixes #70.
Added second texcoord support in OgreImporter utility.
Refactor build scripts.

- Close issue #67, Urho3D iOS library should be built correctly now (either as single arch or as multiple archs Mach-O universal binary). Urho3D library build for Mac OS X and iOS platforms do not rely on CMake hack 'object-collecting' approach anymore. It uses Apple static linker 'ld' tool to merge all objects from third-party *.a directly.
- Add new custom target (Urho3D_universal) for iOS platform to build a single Mach-O universal binary library consists of both iphoneos (universal ARM archs) and iphonesimulator (i386 arch).
- Introduce PLATFORM_PREFIX (ios-, raspi-, android-) to prefix the build and output directories (Build, Bin, Lib).
- Correct Xcode-specific build setting for Mac OS X desktop build to use the latest OS X SDK but set deployment target to current OS X of the build system, unless CMAKE_OSX_DEPLOYMENT_TARGET is set explicitly to build for other target.
- Temporary workaround for CMake/Xcode generator bug where it always appends '/build' path element to SYMROOT attribute and as such the items in Products are always rendered as red as if they are not yet built.
- Change Assimp target to use setup_library() macro so that it gets the same settings (and workaround) as all other targets.
- Add a conditional check to prevent MSVC to build 'buildvm-android' target as it is not supported at this moment.
Bump required CMake version.
Do not use PCH on AssImp contrib source files, as they're not all prepared for that.
