Bug 975708: Fix jboss java7 marker regression

Due to a regression introduced by c3e63de3c7f84cd62df99634dc58371cfd19fd6c, the initial java7
configuration was not being updated properly during setup. Newly created apps using the buggy
cart will default to java6 until the next Git push, at which point java7 will be correctly
enabled.

Fix setup logic to correctly configure java7 for new applications.

Bug 974786: Scaled gear hot deploy logic fix

Make the `gear` script `--hot-deploy` option require an explicit boolean argument
so that the option overrides a repo check for the hot_deploy marker.

Bug 975794: Use install to create volatile environment variables

Variables which are volatile (in that they may be modified later by the cartridge and
are expected to persist between version upgrades) shouldn't be created via the `env`
system in the cartridge unless they are ERB based; otherwise, the variables will overwrite
already created files in instantiated cartridges each time an upgrade occurs.

Create these variables in the `install` script so that they are primed during new cartridge
installation and not touched during subsequent version upgrades.
