Used html module to unescape html characters

[Blackmamoth]

Related Issue

While displaying question titles in the panel, if the question contained and some character like '"' (double quote) it was displayed as its corresponding html escape character which is '"' which didn't seem human readable at all if there multiple html escape characters in a title.

Closes: #184

Describe the changes you've made

I created a function which uses the built in html module to unescape those characters from that particular title.
