Title: Issue #1707: Improves stringByRemovingScriptsAndStrippingHTML performance

After a profiling session, i found out that the following method was performing extremely time-consuming operations (Main Thread):

**Class: NSString+Helpers**
```
- (NSString *)stringByRemovingScriptsAndStrippingHTML;
```

The most lengthy OP is the NSRegularExpression allocation itself. Let's minimize that by using a singleton instead.
