Support of "publish" function

[fireproofsocks]

Should have the ability to push files from the "assets/" folder to the web directory. Along with this should be support of dev'ing inside the MODX_CORE_PATH -- Repoman should see where things are installed.

If the repo path is determined to be inside the core/components/, then:

• "update" command should trigger a publish
• Creating a xxxxx.core_path system setting is not necessary
• Creating a xxxxx.assets_path / xxxx.assets_url system setting is not necessary

Second thought here... this may be trickier than I thought because Media Sources MUST reference paths inside of the MODX webroot. With version 1.1.1 there is a dedicated Repoman Media Source pointing to MODX web root... the publishing action wouldn't take effect until assets are copied from the original assets directory (which could be above webroot) to the publicly visible position inside assets/components/
