Error 413 while saving configuration

[demik]

We had an issue saving configuration after a while.
"Save Buton" would be doing nothing and resulted of an error 413 in node console

POST /dhcp_config_save 413 77.853 ms - 108
Turns out the default size limits for POST data are too small. Our configuration file is a little less than 100kB.
Increasing default values resolve this issue. Proposed patch:
