A feature like cargo search

[MartinNowak]

So I've tested the Rust package manager and it has a nice feature to search available packages.

$ cargo search gl
Updating registry `https://github.com/rust-lang/crates.io-index`
gfx_gl (0.1.4)           OpenGL bindings for gfx, based on gl-rs
gl_common (0.0.4)        Common glue for libraries using gl-rs
gl_generator (0.0.27)    Syntax extension for creating bindings to the Khronos OpenGL and related APIs
gl (0.0.12)              OpenGL bindings
gfx_device_gl (0.5.0)    OpenGL backend for gfx-rs
glutin (0.3.5)           Cross-plaform OpenGL context provider.
kugel (0.0.2)            Rust-oriented OpenGL wrapper.
khronos_api (0.0.8)      Khronos API XML descriptions for gl_generator
freetypegl (0.1.0)       Rust build helpers and bindings for freetype-gl.
nice_glfw (1.0.1)        Create a modern GL context with glfw

It's also nice that it says when its package list cache is updated.

The easiest way of doing this is to make use of the dub-registry api.

I went some way towards that, but never finished it, I'll put it higher to the top of my to-do list.

Maybe there is something both simpler and more useful.

The dub registry command would simply opens http://code.dlang.org

• the registry page is already designed for package discovery, searchable, and have categories
• it is very common to want to reach this page to bump the version of a managed package. I have a script to do this faster.

I can implement it if there is approval.

It's fairly easy to implement b/c dub-registry already has a better search functionality now. The only thing needed is to integrate it with the API.

[MartinNowak]

Implementation done, still waiting for dlang/dub-registry#121 to be deployed.

[s-ludwig]

Deployment is done now.

[MartinNowak]

Deployment is done now.

Nice, tests pass as well.

[p0nce]

Yay!

[MartinNowak]

I left-justified the package names and versions for better readability.
Now we only need a xapian binding for better search results ;).

[s-ludwig]

Okay, looks good.

I added a call to .array to avoid the map.filter chain in Dub.searchPackages to execute the GET request multiple times.
