As there will likely be extensions bundled with the 1.31 release that
depend upon other extensions, we should have the installer prevent users
from enabling extensions that depend on other, not-enabled extensions.
We can build a dependency map from extension.json's "requires"
component. On the client-side, we'll first disable all checkboxes that
require other extensions, and evaluate each checkbox click, updating the
disabled checkboxes as possible.
This required some refactoring of how ExtensionRegistry reports issues
with dependency resolution so we could get a list of what was missing.
While we're at it, sort the extensions under headings by type.
This does not support skins that have dependencies yet (T186092).

I was bored. What? Don't look at me that way.
I mostly targetted mixed tabs and spaces, but others were not spared.
Note that some of the whitespace changes are inside HTML output,
extended regexps or SQL snippets.

There are some extensoins that depend upon another extension or skin,
usually in different ways:
* A constant that is added in the dependency extension, and the
existence of is checked for. This is problematic because it requires a
specific load order.
* Checking whether a specific class exists. This is problematic because
it is extremely fragile, and breaks whenever the class is renamed.
* Checking ExtensionRegistry::isLoaded(). This is mostly there, but it
only checks at runtime, and doesn't provide any machine readable data.
Furthermore, developers implement each one differently, with very little
standardization.
With this, extensions may now specify what other extensions they depend
on. This is for explicit *hard* dependencies that must be installed.
For example:
"requires": {
"MediaWiki": ">= 1.25.0",
"extensions": {
"FakeExtension": "*"
},
"skins": {
"FakeSkin": "*"
}
}
This would add a minimum requirement on MediaWiki 1.25.0+ (already
implemented), as well as the requirement that the FakeExtension extension
needs to be installed, as well as the FakeSkin skin. A wildcard (*) is
used instead of an explicit version requirement as many extensions do
not actually version themselves, and there is no consistent versioning
scheme yet.

This allows us to put other requirements more easily into extension
registration, such as skins and/or extensions.
