GUI walletimport RPC call added

most of the code was in bitcoingui. i tried to make it clean and used
QInputDialog instead of making a model for the wallet just to create the
dialog. moreso, that code would be out of rpcdump space but still using
code mostly from rpc. i decided neither is really the best option and
used only what i needed from rpcdump.
wallet import update
chmod 775 for build_detect_platform
far emit() workaround, small gui layout tweaks
Merge branch 'master' of https://github.com/tryphe/clams-importwalletgui into walletimportui
remove isDialogOK check
remove string lenght check for importwallet command
removing uneeded debug messages
Merge pull request #52 from l0rdicon/walletimportui
