Igor Kushnir 61eb4e08fe Add options to limit input phrase length 
When a long text is accidentally selected or copied while the scan popup
is on, Goldendict spends a lot of CPU time to gradually create a
"No translation..." article. When translation of huge (e.g. 15 MB) text
from the clipboard is (accidentally) requested, Goldendict freezes for a
while. Turning the added input phrase limit option on eliminates this
waste of the CPU time.

I have implemented these options primarily for selection and clipboard,
but they also affect mouse-over translation on Windows and command line
translation requests. This is mostly because I did not bother to limit
the options' scope. I guess hovering over an extremely long text without
spaces (e.g. Base64-encoded) could cause the same performance issue on
Windows. The command-line translation could be requested from a script
that integrates Goldendict with some other application, from which long
text could be sent for translation by accident.

I hope that the default value of 200 characters will be sufficient for
just about any real-world user input in any language. The option is on
by default, because the default length limit is generous and any longer
text is unlikely to be sent for translation intentionally. My personal
preference for the input phrase length limit is 100 symbols.

ArticleView::pasteTriggered() didn't call QString::simplified() on the
text retrieved from the clipboard. I assumed this was an oversight, so
now it *is* called - indirectly, via Preferences::sanitizeInputPhrase().
