Development to Master

We are now merging all our changes from Development into master. Here some highlights:

* Bootstrap Theme implementation
 * MPOS Theme is now deprecated
 * Bootstrap theme with two color schemes
* Coin Class Integration
 * Change the behaviour of Hashrate, Estimated Shares, Estimated diff for your specific coin using our coin classes
 * `coin_base.class.php` includes all existing methods to run `scrypt` and `sha256d` out of the box
 * `coin_<algo>.class.php` can be used to overwrite the base methods
* New getbalance implementation
 * You can chose via config if uncomfirmed blocks should be deducted from balance (default) or not (some coins have issues with getbalance)
* Cloudflare HTTP Header
 * @Contex added Cloudflare header support, thanks!
* **DB UPGRADE REQUIRED** Baseline Shares Removed
 * This is a big one too, we now display proper diff1 stratum share counts in MPOS! No more baselining
 * Please run the upgrade script to update your past rounds to the new display format
* Database Upgrade Script
 * MPOS Updates just got a lot easier: We now offer a simple script which updates your DB automatically
 * All past SQL upgrade files since 0.0.1 have been removed and integrated to the script
 * It allows to update from any version since 0.0.1 to the latest 0.0.8 automatically

As usual, please follow the (updated) upgrade guide in the wiki to update to the latest version of MPOS!
