Web Inspector: refactor SourceFrame to simplify implementing of js beautifier.

* do not store breakpoints in SourceFrame (in SourceFrame._breakpoints and SourceFrame._textModel) since we already store them in BreakpointManager
* move user input processing from SourceFrame to SourceFrameController, since SourceFrame doesn't know about line -> sourceID mapping and therefore is unable to modify model directly (set breakpoint and such)
* introduce ScriptBreakpointView class that represents a single blue breakpoint bar on a source frame line gutter
* BreakpointManager shouldn't require breakpoint url to set a breakpoint
