add required PHP modules to composer.json

[Flyingmana]

as we absolutely require some php extensions like mbstring, we should make sure this is visible in the composer.json

Here is what PHPStorm propose for app directory:

+   "ext-curl": "*",   (php-curl)
+   "ext-gd": "*",   (php-gd)
+   "ext-json": "*",   (php-json)
+   "ext-mbstring": "*",   (php-mbstring)
+   "ext-pdo": "*",   (php-mysql)
+   "ext-simplexml": "*",   (php-xml)
+   "ext-dom": "*",   (php-xml)
    "ext-libxml": "*",
+   "ext-soap": "*",   (php-soap)
    "ext-iconv": "*",
    "ext-zlib": "*",
    "ext-ftp": "*",

now we need to find out, which of them are optional :/
Iam pretty sure the ftp one is not generally needed?

Mage_Dataflow is using ext-ftp, and I think Mage_Backup too but it's disabled by default.

I updated my anwser by adding php package name.
Not sure who provides "ext-libxml", perhaps php-xml?
I checked my packages, php-iconv is not installed.
I don't remember if php-soap is required or not.

I don't remember if php-soap is required or not.

Yes it is, it's used by Mage_Api and I some other core modules.
