Fix line ending

Change to UNIX
Apply some PHP best practice

include 'file' instead of include('file'), removing closing PHP tag
Change mysql_numrows() calls to mysql_num_rows()

mysql_numrows() is deprecated
Remove composer related files

They will be automatically created by composer upon `composer install`
Also add a .gitkeep file to 3rdparty/ to preserve empty directory
Fix some file/line ending madness

Trailing white space, closing PHP tag are both unneeded
