Remove phonegap build files from repository for clean rebases/maintenance

This commit removes the build files associated with Phonegap's build
process. This should remove the extra cruft from the project's
repository and make it easier to isolate the changes that the dev team
makes from the changes that Phonegap makes.
Remove resources/css, build/.../full-page-master-bundle.js,
bootstrap.js from repo

This commit removes a series of compiled files from the repo to better
isolate developer changes from compiled changes to the project. This
commit implies that the project will need to be rebuilt in order to
run after a git clone.
Finalize .gitignore to prevent re-addition of compiled files to repo.

Prior to this commit, the repository was maintaining the state of
several compiled files in the phonegap, resources and build
subdirectories. This commit finalizes the edits made to the .gitignore
file such that these directories are not re-added to the repository.
