Custom themes as option

As suggested in #1258

The reason I hesitate on this is that I'm torn between user choice and splitting the user base. As it is now, when someone sets their custom profile style/background, they can expect that other Enhanced Steam users will see these changes. If there is an option to disable seeing other users custom themes, it will fall into the categories of "Not using Enhanced Steam / Using Enhanced Steam with option turned on / Using Enhanced Steam with option turned off".

The better solution would be to perhaps update the clear theme (which is, I believe, the source of this issue) so that the user's header text stands out more.

I get your point. The reason I jumped on adding the option short after it was suggested is because I happened to came across the same issue in the past. Custom themes will be enabled by default anyway, and unless a user get bothered by those he won't look into disabling them, that's why I think is good to have the option.
We could allow the users to toggle custom themes but let them to make use of custom themes for their own profiles only if they enable the visibility of custom themes for other's profiles too.

Anyway, just my thoughts. Whatever you decide I'm OK with it.
