Documentation updates

• All docs pages now have distinct titles, such as Scaffolding · Twitter Bootstrap.
• Updated the Apple touch icons (now black on black instead of the blue grid) and fixed the links to them in the docs.
• Added new global styles docs section to the Scaffolding page.
  • Required use of HTML5 doctype
  • Overview of global typographic and links details
  • Mention of our embedded CSS reset via Normalize.css
• Added version number to the download button on the docs homepage.
• Updated progress bars section to simplify how the classes stack and more clearly indicate the available optional classes and styles.
• Added a new example, SoundReady.fm, to the homepage
• Added various sizes to the docs for button groups

Resolved bugs

• Removed all IE7 hacks and floats from .input-prepend and .input-append, however, this requires you to ensure there is no whitespace in your code between .add-on and the input.
• In .input-prepend and .input-append, added ability to use add-ons on both sides when you chain the selectors.
• Updated lingering .btn-dark reference to .btn-inverse.
• Fixed issue with content being cut off in .tab-content for tabbable sections.
• Updated .navbar .container to use width: auto; to start and then reset the fixed widths via the #gridSystem mixin (it's a little dirty, but required to avoid adding another class).
• Modal footer buttons are now aligned by their parent via text-align: right; instead of float: right on the button level. This was changed to allow the use of .pull-left and .pull-right to align buttons easily. Double check your button order with this change!
• Fixed problem where default striped progress bar was green instead of blue.
• Fixed CSS selector used for input and textarea grid sizes to properly apply the CSS (was input > .span* and now is input.span*).
