MultiPHP INI Editor (basic mode) should offer more helpful advice / guidance

As a System Administrator, I'd like to see more useful and consistent advice/guidance being given when I'm looking at the MultiPHP INI Editor, so as to help me make better decisions.

Example, for each PHP Directive. could:

1. Hyperlink to the corresponding official (or other) documentation.

2. Be consistent with providing information about
i. Min, Max, and Default/Recommended values for each.
ii. Unlimited values for each. Is -1 always valid, or not, for this? Maybe sometimes it's 0?
Right now the above information is inconsistently provided per directive

3. More information about what constitutes valid input. For example, for post_max_size, I can deduce that 'M' is the correct notation for Mb, where 8M is the default. But is 'G' for Gb allowed too? Sure, you can (and should) trap this with an error message if the input is incorrect. But better to know up-front.
