Add "Change Package" button for Settings page enter code here and for Renew page in Nextpost 4.0 and higher

Nextpost 4.0 and higher

• Adds a "Change Package" button to Profile Settings page
• Adds a "Change Package" button to Renew page (when subscription expired)
• Checks for account count and just offers to change into packages where the allowed account count >= the existing accounts
• Added extra security to prevent someone of downgrading with more accounts then allowed

Add translation of "Change Package" to your messages.po

Example: Let's translate "Change Package" text to Russian in /app/locale/ru-RU/messages.po Just add new line with:

#: 
msgid "Change Package"
msgstr "Изменить тариф"

Find "pay" function and replace line:

To

if (!$SelectedPackage->get("is_public") && $SelectedPackage->get("id") != $AuthUser->get("package_id") || $SelectedPackage->get("monthly_price") <= 0 ) {
