Six new walks on my website

I've just updated my website with six new walks:

1033	London Loop: Erith to Farnborough, and then on to Chiselhurst	23.5	19/01/2019
1032	London Loop from Rainham to Purfleet, then on to Basildon and Pitsea	23.6	12/01/2019
1031	London Loop: Loughton to Rainham	23.7	05/01/2019
1030	London Loop: High Barnet to Loughton	20.7	01/01/2019
1029	Ebor Way: York to Wetherby	23.3	28/12/2018
1028	Gipping Valley River Path: Stowmarket to Ipswich	20.9	22/12/2018

There are one in Suffolk and another in Yorkshire to complete 2018, and four around the London Loop to start 2019.

I've also fixed a few bugs that were preventing links from working on the named walk pages.
