Feature Request - Base Conversion

[jaeggr]

Testing this out a little, the app already understands input of both hex and binary and displays their values in decimal. But it would be really handy to specify the desired output format.

Something like 0b101 %x would return 0x5, or something like that (currently it returns 5 in decimal) Or similarly 0xa %b would return 0b1010 instead of 10
