update dependencies documentation

[realsobek]

at the website: https://github.com/bibliocoll/JournalTouch#dependencies

you can read: PHP 5.3 or newer ([http://www.php.net]), please use the most up-to-date version you have available

Please, remove "5.3 or newer".

My story: The other day I tried installing JournalTouch 0.3-197-g27ce9e6 on CentOS 7 x86_64. firefox http://journaltouch/index.php resulted in dark blue bar at the top. about, tags, portfolio buttons were shown on the bar. The website was white, no other function.

tail -f /var/log/httpd/error_log showed this line: [Sun Apr 03 13:43:39.877648 2016] [:error] [pid 2536] [client 192.168.2.101:50599] PHP Fatal error: Call to undefined function array_column() in /var/www/html/bibliocoll-JournalTouch-0.3-197-g27ce9e6/index.php on line 108, referer: http://192.168.2.105/admin/

According to documentation: http://php.net/manual/en/function.array-column.php the function is 'PHP 5 >= 5.5.0' only.

Stock PHP package on CentOS 7 is version 5.4.16-36.el7_1 Luckily, I could work around with help of RH-SCL repo: yum install -y centos-release-scl

I am going to update to JournalTouch 0.4.1 :)

that is a good catch, thank you. i've updated the readme for the develop branch.

i'm currently only testing on 5.5., 5.6. and 7.0.* internally, and i would be fine with dropping support for the older versions. any objections there, @tzeumer ?

[tzeumer]

I never thought too much (or wrote anything myself) about php versions. So, no objections from me.

[krugar]

5.5+ it is, then. might progress to 5.6+ or 7+ as php.net begin sunsetting the older versions.

I found one more mention of PHP 5.3 in the wiki at: https://github.com/bibliocoll/JournalTouch/wiki/Installation-&-Setup

[krugar]

changed that to 5.5+ as well, however the rest of that page needs a complete overhaul as well
