added a 'greedy learning' mechanismn which will cause that a 'fresh'

Browse Source 
yacy will load linked web pages from search results until the total
number of web pages reaches 15000. This shall give fresh peers a 'boost'
to get faster a personalized search index.

# greedy learning: fast information acquisition heuristic for new peers
# to make greedy learning work, it must be enabled in the network definition
# the user may switch it off at any time, but if the automatic learning limit is reached
# then the active flag is set to false automatically and this will switch to that state
# automatically by the cleanup process each time if the user switches it on again.
# While the switch in on, it will cause that the user-submitted search will be done along
# with some heuristics like: loading linked documents and adding a twitter search.
# When the learning mode is finished, the user may switch on individual heuristics by himself.
