pfSense

Completed #5407

Teach pfSense-upgrade to run gitsync after upgrade

Correct Form_TextArea -> Form_Textarea

List CSS file in alpha order

Added use of class autoloading (GUI stuff only)

Any GUI script that loads the guiconfig.inc file will have access to
the autoloader.

Define user-agent on pfSense-upgrade

Re-add host_uuid user-agent option lost during bootstrap import. While here, change its name to be more clear what it does

Tunable value can be zero, use isset() to validate it

Merge pull request #2101 from doktornotor/patch-5

Remove the last usage cases of $config['ipsec']['enable'].

IPSEC is always on in 2.3, where necessary (IPSEC rules, IPSEC daemon), we check the existence of phase 1 entries.
