Mini Shell

1) For Languages add [[language]] in SQL and in settings.php
2) We add /language/[[language]].zip for all language
* Download the language files from:
http://community.mybb.com/mods.php?action=browse&category=translations
check for exact structure of language, if it match then only update the language pack.
Remove the install/ directory from language pack
3) Database Engine MySQL Improved
4) Leave ACP Pin blank
5) Copy the cache/theme/theme1 and cache/theme/theme2 folder from manual (if css is not generated) (Not required since 1.8.33)(Required again in 1.8.34)
6) Verify the steps in manual upgrade and auto upgrade (debug mode) and confirm the steps are correct. The auto upgrade is complicated.
7) Update the file org_upgrade.php (from original zip /install/upgrade.php) and mod_upgrade.php (from original zip + our changes) of the new version. This change is for auto upgrade.
We have commented the login part and added the following lines :

		// Softaculous Change
		echo '<softupdate_ver>'.$next_update_version.'</softupdate_ver>';
8) Update the file index.php (from original zip /admin/index.php) and _index.php (from original zip + our changes) of the new version. This change is for auto upgrade from version less than 1.8
We have added if statements for login part
9) PHP REQUIREMENT LINK: https://docs.mybb.com/1.8/install/requirements/ ( We have kept requirement to 7.0.0 bcoz it was throwing error on PHP < 7.0 , https://github.com/mybb/mybb/issues/4705 ). Check if this is fixed in next version, check and change version accordingly. Reverted to PHP 5.5.0 in 1.8.35, as it works fine now on PHP < 7.0.
