* The information extracted from Homebrew's JSON command now also
includes information about linked keg and installations.
* The mapped versions in the App class now contain information about
the Homebrew installation as well.
* A HomebrewDiagnostics class has been added, which is currently able
to detect conflicts between the `php` formulae of core and the
`shivammathur/php` tap (which is currently an issue, see #54)
* Alerts are now displayed as critical if they are truly problematic.
* PhpInstallation was renamed to ActivePhpInstallation, to make room
for a generic PhpInstallation object which contains cached info.
* Shell.pipe() now returns the contents of standardError if
standardOutput was empty and there was some data in standardError.
This makes it easier to debug the output of commands that output to
standardError. (For example, failed brew commands might.)
Using `php-config --ini-dir` seems to fail on PHP 7.2 and below, likely
because said option was not available in these earlier versions. Because
all we need are the additional .ini files, calling php_ini_scanned_files
is a better solution since it is supported from PHP 5 and up.
This commit fixes the crash issue that was caused by running the failing
`php-config` command.
