... by creating a default run configuration.

- created protocol class as basis for different paste servers
- removed custom classes and replaced functionality with
  simple QHttp* usage
- removed poster and fetcher classes copied from cpaster
  application. It not getting updated anyways in creator
- Known issue: Listing does not update, when user changes
  protocol
- TODO: add pastebin.ca support. Code is done already, just
  needs to be placed inside plugin.

Thiago changed the way buildkeys are parsed, thus to reintroduce the
patched plugin loader, the changes to the build parser must be ported to

the startup project are both null and the same.

Also fix a small bug with the import label.

Remove unused code.

Don't add -spec foo to the additional Arguments if foo is the same as
the default mkspec. This makes the common case better, while breaking if
you have QMAKESPEC set in teh environment and used -spec foo to override
it.

Not much error reporting etc yet. Application TRK needs to be
running on device.
