8075: Improve Eclipse development experience

[RealCLanger]

This PR merely updates the .classpath files to the state they would end up in when you do Maven -> Update project ... in current Eclipse.

There were only 2 manual changes:

1. I updated/corrected application/org.openjdk.jmc.flightrecorder.dependencyview/build.properties
2. I removed application/org.openjdk.jmc.browser.attach/.settings/org.eclipse.jdt.core.prefs because it gets generated upon Eclipse import anyway. Unfortunately it does not serve the use as a workaround for deselecting the --release compiler option.

In addition to that, I polished the devguide a little bit to hopefully make it more clear and stringent.
