haproxy_ctld_daemon.rb: Fix backtrace option

The haproxy_ctld_daemon.rb script in the haproxy cartridge had a typo:
':backgrace' instead of ':backtrace'.

This typo appears to have been present since haproxy_ctld_daemon.rb was
introduced in commit ee8cebbe1adb351a3b80ca3fda4f047aee8fac1b.
process_templates need to be String literals
bin/* needs to be executable
Mention EOL chacacters
Mention chmod.
Add Windows-friendly instructions
Application's action hooks follow the same semantics as cartridge control scripts
A typo
Add sections for readability
Minor tweak in wording
Allow plugin carts to reside either on web-framework or non web-framework carts.
HA-proxy cart manifest will say it will reside with web-framework (earlier it was done in the reverse order).
Remove stale file manifest.yml.fedora from openshift-origin-cartridge-php
Correctly create custom apps
