Showcase gallery

[miphe]

Showcase gallery feature doesn't look good enough. Refactor and redesign it all please.

Requirements:

• Small tags (icons) to represent what type of showcase item this is. For instance a showcase item may be the creation of a small JS MV* library which depends on LoDash, then the icons "JS", "Library" and "LoDash" would be displayed by the item. Some showcase items are not graphical at all, so we can not solely rely on graphics/photo being the only source of information in the showcase list before item is clicked.
• Filter by tag. When clicking on a tag (icon) I only want to see items with that tag. This is especially interesting because if the site running this theme is a showcase for a developer who has showcase items about javascript, but also about C++. In case this person is looking for a C++ position, it would be useful for his future employer to filter on only those showcase items, getting rid of all insignificant JS stuffs. There also needs to be an easy way to clear the filter.
• More information or more/larger images about the item when you hover the item.
