[horde] Status dev-FRAMEWORK_6_0

[Michael Schlueter]

Hello Ralf,

I did new installation based on the dev-FRAMEWORK_6_0 version with 
"composer create-project horde/bundle ." and added all the other 
packages from packagist.org also with the version dev-FRAMEWORK_6_0.

Looks like there is an integration error in Imap_client. Could you 
please have a look into the commit:
https://github.com/horde/Imap_Client/commit/2fd03b199f25fe3573bf753cc6227647a75cc85b
Some of the __serialize/__unserialize functions are doubled now.

Sometimes I get a messed up url especially when logging into imp to 
authenticate the imap server:
http://192.168.1.100/horde/login.php?url%5Banchor%5D=&url%5Bparameters%5D%5B_t%5D=87234687&url%5Bparameters%5D%5B_h%5D=234-kj45jhg2435jhg&url%5Braw%5D=1&url%5Burl%5D=http%3A%2F%2F192.168.1.100%2Fimp%2F&app=imp
Do you know where I can have a deeper look to solve this issue?

strftime() is deprecated but it is used it some parts. Do you know how 
to replace it?

DEBUG: HORDE [horde] PHP ERROR: Function strftime() is deprecated [pid 
123456 on line 495 of 
"/srv/www/horde-dev/vendor/horde/horde/config/prefs.php"]
strftime() is also used in 
/srv/www/horde-dev/vendor/horde/horde/lib/LoginTasks/Task/LastLogin.php 
two times, /srv/www/horde-dev/vendor/horde/date/lib/Horde/Date.php (Line 
1217, 1219) and 
/srv/www/horde-dev/vendor/horde/horde/lib/View/Topbar.php (line 84).

I fixed some PHP Errors and created pull requests. Please have a look 
and give me feedback if I should change them.

Thanks
Michael
