Update videinvoke: maximize, eclim, load once

Re-enable resizing -- it works in Precise.

Add maximize on windows.

Make ctrlp's window half the resized window height so I can see more
results.

Add eclim settings that are guarded by an eclim command. Unfortunately,
this doesn't ensure that eclim is actually running (just that it's
loaded).

Only do resizing and plugin setup on first call to videinvoke. Do
file-specific stuff every time.
Give list and longest at the same time in wildmenu

When completing on vim's cmdline, don't require an extra Tab to show the
list. Give me the longest completion and the list of matches so I can
start narrowing down the list right away (or hit tab again to iterate
through the matches).
Update sontek link to one that works
Use noremap instead of map where possible
Allow my autocomplete in cmdwin

I don't use Tab for ins-completion, so use my normal C-Space for smart
completion in cmdwin (which uses the "guess" completion).
