UI improvement, User can specify more options at memory dump analysis scene & changing setting is cancelable after open the settings pannel.

1. User can specify more options at memory dump analysis scene.

Analyse could be faild caused by OOM(exceed limit of maximum length of array) if the dump file is very large. This problem can be solved by specify discard-object options. see: Eclipse help . Improve UI so user can specify those options.

2. UI improvement, user can cancel changing the settings (re-analysis dump file) after they open the setting panel in dump analysis scene.

before: dump analysis cache will dispose once user click 'Setting' button, it does not make sense. now: dispose and re-analyse will performd sequencely only after use submit the new settings, but if user click the 'cancel' button after open the settins pannel, the pannel will closed and nothing else would happend.

@XuPengfei-1020 Thanks for the contribution. Please sign the eca.

I'll review this patch this week.

Update:

• Signed the eca.
• Capitalize first letter in analysis setting panel.
• Remove 'Discard' button. User can re-analyse the dump file by click 'Setting' button, or discard dump file and analysis cache in file-manage page. The 'Discard' button is redundant, you are right.

We used the jifa to parse the super large dump files on linux server several times, it helpe us to location the rare memory lake point in our production environment. Thinks! Great tool!
