Release Candidate 7 is Live

Release Candidate 7 is out. It is a bug fix release for RC6.

Our green flag test blockchain launch worked but it uncovered a flaw in our installer versions. This release is a bug fix release to address that flaw. You should read the RC6 changes below if this is your first time installing since RC5.
Thanks to @dkackman for implementing an early exit of the GUI if you run npm run build without being in the venv.
chia netspace now defaults to 1000 blocks to mirror the GUI.
The installer build process was spruced up some.

Setting difficulty way too low on the testnet_6 launch revealed a Timelord edge case. The full node was hardcoding the default difficulty if block height is < EPOCH_BLOCKS. However there were many overlapping blocks, so none of the blocks reached the height, and therefore the timelord infused the wrong difficulty.
Fixed a race condition in the Timelord, where it took time to update the state, so it ignored the new_peak_timelord form the full_node, which should have reset the timelord to a good state.
Wallet notoriously showed “not synced” when it was in sync.
Installers were not correctly placing root TLS certificates into the bundle.
Weight proofs had a logic typo.
There was a typo in chia netspace. Thanks @altendky.
There was a typo in chia plots. Thanks @adamfiddler.
