Some files don't contain a line separator ('\n') at the end. Add the
missing eol.

In POSIX, all lines of text should end with a newline character by
definition. See

section 3.397 for more.

See https://gist.github.com/jacknagel/1020172 for a gist of the issue.

The .project and important .classpath files are a part of an Android Eclipse
project, and their changes should be stored in the repository. Although there
may be a case for ignoring these files in very rare situations, they don't
justify belonging in a generic template.

The .project file is generally recreatable with a new import without
difficulty, but it still may have important configuration such as extra build
steps. More importantly, .classpath is absolutely essential for a project to
build correctly and cannot be automatically generated unless there is nothing
extra on the classpath.

Reverts commit 3ad9edaa.

When exporting a signed .apk, Ecipse creates a proguard folder in the root directory. It should not be commited.

Added local properties, updated how generated files are detected, added OS Cruft (useless stuff added by windows/mac)
