NetvClientDetect 


REVISION HISTORY
---
Version 2.7.1  // 
---
- bug-fix: fullscreen parameter
- added NetvClientDetect.clientInfo['flash_version']  (array with version parts, i.e. [10, 1, 102])

---
Version 2.7  //
---
- added Flash sub-version detection (e.g. 9.0.115 instead of only 9)
- added Chrome detection
- added FlashVars attribute for Flash Player 6+

---
Version 2.6  //bug-fixing
---

---
Version 2.5  //support badbrowsers version compare
---
- added badbrowsers special compare for older browsers e.g. {os_name:'Mac',br_name:'Safari',br_ver:{compare:'<=',value:'419'}}

---
Version 2.4  //support os iPad, iPhone, iPod
---
- get this params to flash "_stageWidth" and "_stageHeight"

---
Version 2.3  //remind to update 'detector_version' in function!
---
- get this params to flash "_stageWidth" and "_stageHeight"

---
Version 2.2  //remind to update 'detector_version' in function!
---
- bugfix ie if no flash installed "flashVersion undefined"

---
Version 2.1  //remind to update 'detector_version' in function!
---
- added detector_version

---
Version 2.0  //remind to update 'detector_version' in function!
---
ajax support:
- xx=function() for all functions, 
- new getFlashVersion for ie (modified from google swfobject)
- removed closing object slash object open tag in function showflash()

usage 
<div id="swf-container" style=""><!-- swf gets here by innerHTML --></div>
